[36]

S32 step pulses in the received for checking continuity of radar signals missing pulse while extracting identifying a so as to provide of equations is determined through 1.

[37]

[Expressions1]

[38]

[39]

Wherein, N extraction pulse number, n during the weight it will decrease of the pulse is missed pulse number to.

[40]

For checking continuity can be obtained from such consistency during the pulse in the present invention is time-consuming for checking continuity of speeding the computation of expressions to reduce the calculates an simply using 2.

[41]

[Expressions2]

[42]

[43]

Wherein. Number of pulse extraction N, PRImean includes an emitter of average PRI (Pulse Repetition Interval), power in pulse-TOA. measurement time. Therefore, expressions total measurement time of denominator 2 exhibits a pulse train.

[44]

Such checking continuity the certain level of it is preferable that the interval in.

[45]

S33 step, radar signal comprised of orientation components distributed or more range by the application of signals if is. processing noise.

[46]

S34 step, pulse group of signals lobe whether for of this in determining a is refers to. S35 and S36 step S31 from up to step S34 according to the result of step S34 to the step of determining the confidence level with a to described hereinafter.

[47]

S34 therefore, the step also for reference a 4.

[48]

A checked of lobes radar signal Figure 4 according to an embodiment of the present invention method is to a flow chart.

[49]

Also as shown in 4, the above-mentioned of Figure 3 S34 a last of the group of pulse pulse step a user selects the pulse (S41), pulse group to manage user login/logout of pulses pulse amplitude to the step of performing a fine (S42), differentiated value is larger than or equal to O (S43) to determine whether the step, said S43 step of a liquid if this has a differentiated value or more O increasing number 1 device and a method for using the sum of the value of 1 (S44) calculating the, 0 said S43 step of a liquid if this has a differentiated value of less than 1 to reduce number 1 device and a method for calculating the using the sum of the value of (S45), calculated step S45 and said S44 using a value increased or reduced rate calculating the preset and increase/decrease and (S46), comparing a reference value includes (S47).

[50]

S41 last group of pulse step detecting a pulse as as illustrated at, last pulse when a mobile station is determined to increase/decrease is step proceeds S46 is the dynamic programming component determines.

[51]

Therefore, pulse group of pulse are finally pulse if not, last pulse from a pulse of original group pulse i.e. up to. is done step is repeated S45 to step S42.

[52]

S42 and S43 step pulse group to manage user login/logout using pulse amplitude of each pulse performs a, the evaluation regarding the differentiated value is a fingerprint.

[53]

Wherein differential equations arithmetic used in the basic so as to provide of equations (a) and a equal of 3. State of the SP heads and, the present invention refers to less than 0 is differentiated value larger than or equal to 0 that it focuses whether presence or an absence lobe of a radar signal received is the expressions 3 of differential equations is used in the arithmetic (b).

[54]

[Expressions3]

[55]

[56]

In 3 said expressions, Si second pulse pulse amplitude the i, Si+1 i+1 the second pulse pulse amplitude, Ti second pulse time of arrival of the i, Ti+1 i+1 time of arrival of the second pulse, a α Ti+1-Ti value the reciprocal of.

[57]

S44 step O is differentiated value of the amplitude of pulses in step S43 a length different from each receives and transmits a navigation signal number of any pulse of pulse amplitude pulse and then a length different from each O is differentiated value 1 number increased thereto which records the outputs a using the sum of the value of 1.

[58]

On the other hand, step S45 alternatively step S44 is differentiated value of pulse amplitude of less than O of a liquid if this has a differentiated value of the scanned data to a pulse having in any order and then is differentiated value of pulse amplitude of pulses of a O number decreases if less than 1 thereto which records the outputs a using the sum of the value of 1. As described above in step S45 step S42 group to manage user login/logout pulse a process for the same initial pulse from the last pulse and the processing advances, n of such series circuits.

[59]

Now, last group of pulses in step S41 upon detection of pulse, adhesive step S42 can be obtained from step S46.. S46 step S44 and S45 step using results calculated calculating the rate is increased or reduced.

[60]

In the present invention for calculating the increase/decrease rate of expressions using the 4.

[61]

[Expressions4]

[62]

[63]

In 4 said expressions, in step S44 the N (p) counted pulse amplitude of number of a length different from each 0 is differentiated value, counted in step S45 the N (m) is differentiated value of pulse amplitude less than 0, in this case, number, power in pulse-N (T) group to manage user login/logout is total number of pulse.

[64]

S47 is calculated by step S46 step lets rate larger than or equal to is contained the steps of a determiner determines whether less than, less than reference value increase/decrease rate when the pulse group, to which a mobile station belongs the presence of the lobe signal of a radar since determine is for reporting the threat signals, increase/decrease controller if the corresponding radar signal of lobes is not present since the is determined does not reporting threat signals.

[65]

Wherein, with a preset reference value may be any of the values, exceeds a predetermined time before the magnetron properly 500 and system is set between.

[66]

E.g., number group of pulse pulse to be assayed, the reservoir 20 wherein a is two, their differentiated value is counted by the counting results 9 frequencies are increased, 8 frequencies are reduced, in the event of said expressions which appear as if by 4, the increase/decrease (9-8)/ 21 = 0.04762, i.e. is approximately 4.73%. At this time is set in step S47 is a reference value controller lets calculated ramyon 10% less than the client device receives the predetermined signal lobe as typical for the presence of. a mobile station is determined to.

[67]

To another case, number group of pulse pulse to be assayed, the reservoir is placed on the pillow with the examples of the same one between the side of one wherein a is 20, is a reference value is set in step S47 when 10%, their differentiated value is counted by the counting results 15 frequencies are increased, said expressions many sides is shown 3 frequencies are reduced 4 is calculated by the sensitizer (15-3)/ 21 = 0.5743, i.e. is about 57.43%. Therefore, the client device receives the predetermined signal value the reference rate increase/decrease lobe is not present a mobile station is determined to..

[68]

With a 3 also again, in Figure 4 step S35 and S36 invention as described above wherein the signal identified with the presence or absence lobes of radar signal lobe by the presence if a decision is made that the radar signal is high as threat signals magnetron value, it decides that an reliability features with, radar signal of lobes does not exist in the corresponding radar signal is prevented low reliability as threat signals magnetron the system having a high reliability and threat signals. to distinguish threat signals preferably a low-reliability.
