METHOD OF AVOIDING CONTROLLED FLIGHT INTO TERRAIN AND A CONTROLLED FLIGHT INTO TERRAIN AVOIDANCE SYSTEM

A method of avoiding Controlled Flight Into Terrain (CFIT) involves a step of equipping an aircraft with a radar based sensor positioned in an angular orientation directed forward and down, so as to detect ground objects ahead of the aircraft. The radar must have a range of at least 10 Kilometres. A processing unit monitors the radar based sensor. A display remains in an inactive mode until the radar based sensor detects a ground object meeting predetermined parameters. Upon the radar based sensor detecting a ground object the processing unit is programmed to switch the display to the active mode and display a graphic representation of the ground object. The method puts the pilot on alert with an accentuated and focused warning in sufficient time to take appropriate evasive action to avoid a ground obstacle.

Vehicle anticollision radars head-up display - uses windscreen reflected display of light diode matrix indicator

The head-up instrument display system for motor vehicles is for use with vehicle-mounted radar anti-collision equipment. The display of data uses a series of LEDs mounted near the windscreen so that light is reflected from the windscreen to the eyes of the vehicle driver without distracting his attention from the road ahead. The LED matrix can be arranged so that certain patterns or colours indicate the range and bearing of obstructions ahead of the vehicle as detected by the radar. The information is first stored in a register before being passed to the display. The diode matrix (1)(2) may be mounted in a suitable position on top of the dashboard (5) so that the display appears in the driver's line of vision through reflection.

Automotive radar systems and techniques

레이더 탐색 프로세스는 특정 탐색 지역 안에 있는 물체를 탐색하기 위해 FFT 출력 신호의 도함수를 계산하는 단계를 포함한다. 한 실시예에서, 상기 FFT 출력 신호의 제2 도함수의 제로 교차는 물체의 존재를 의미한다. 상기 물체의 범위는 상기 제로 교차가 발생하는 주파수의 함수로 결정된다. 각 레이더 빔과 프로세싱 사이클 안에 물체가 존재하는지 또는 존재하지 않는지를 지시하는 지시자들을 포함하는 탐색 테이블이 또한 설명된다. 적어도 두 개의 상기 지시자들은 상기 탐색 지역 안에 물체가 존재하는지를 탐색하기 위해 결합되며, 상기 안테나 빔들 각각의 범위 게이트를 변화시킴으로써 상기 탐색 지역의 커버리지는 변화될 수 있다. The radar search process includes calculating a derivative of the FFT output signal to search for an object within a particular search area. In one embodiment, the zero crossing of the second derivative of the FFT output signal means the presence of an object. The range of the object is determined as a function of the frequency at which the zero crossings occur. A search table is also described that includes indicators indicating whether or not an object exists within each radar beam and processing cycle. At least two of the indicators are combined to search for the presence of an object in the search area, and by changing the range gate of each of the antenna beams, the coverage of the search area can be changed.

Background information superimposition device - has frosted disc between partially transmitting mirror and background information original

A device for use with a cathode ray projected image by means of which a main picture, in particular a map or similar illustration may have background information superimposed upon it. A partially transmitting mirror device is situated between the front or viewing screen of the cathode ray tube and the viewing aperture for the observer. The device is constructed with a matt or frosted disc (13) between the partially transmitting mirror (6) and the original (10) upon which the background information is contained. The matt or frosted disc (13) acts as a support for the background information.

Elastic wave coordinate meter - detects delay from surface point to detectors on coordinate axes

The meter supplies the coordinates of a point on a surface with respect to two axes. A movable transmitter (3) placed in the neighbourhood of the point (4) emits elastic waves in the air from an initial instant in time. Detectors are placed on the first of the two coordinate axes and detectors are placed on the second of the two coordinate axes. These detectors receive the elastic waves which are delayed with respect to the initial instant as a function of the position of the emitter. A processing system connected to the transmitter and detectors supplies, from the delay times, the coordinalis of the point.

Method and system for displaying target icons correlated to target data integrity

A method is provided for determining the integrity of incoming target data and for assigning and displaying a target icon correlated to the target data integrity. Target data integrity depends on the both accuracy and the timeliness of the position data being broadcast about the target. Target data integrity is monitored continuously to display a target icon correlated to the current integrity level. Changes in the target icon alert the flight crew or other user to changes in target data integrity. The icon attributes used to communicate a change in integrity do not interfere with other icon attributes used to communicate other characteristics of a target.

Patent FR2221862A1

RADAR STABILIZED DIGITAL DEPOSIT INDICATOR

L'invention concerne un radar numérique stabilisé. Il comporte des unités séparées de modulateur-émetteur-récepteur et d'indicateur traitant des signaux d'image numérique. L'unité d'indicateur émet des impulsions de déclenchement en synchronisme avec une horloge, à une fréquence déterminée par le réglage de portée. Le modulateur-émetteur produit un signal d'accusé de réception dans une relation de temps prédéterminée avec l'émission de l'impulsion radar et qui déclenche le balayage du tube à rayons cathodiques. L'invention s'applique notamment à un radar indicateur de gisement installé à bord d'un navire. The invention relates to a stabilized digital radar. It has separate modulator-transceiver and indicator units processing digital image signals. The indicator unit emits trigger pulses in synchronism with a clock, at a frequency determined by the range setting. The modulator-transmitter generates an acknowledgment signal in a predetermined time relationship with the emission of the radar pulse and which initiates scanning of the cathode ray tube. The invention applies in particular to a bearing indicator radar installed on board a ship.
