A method for generating and compressing multi-sweep-frequency radar signals is provided, based on the idea of reducing the power density of signals on a time-frequency domain. By using a method of circumferentially shifting and superposing a single sweep-frequency signal, sweep-frequency signals multiplexed simultaneously at time and frequency are generated, and for the generated multi-sweep-frequency signals, the sweep-frequency signals are multiplexed simultaneously at time and frequency in a single pulse time period. The multi-sweep-frequency signals multiplexed at frequency are used to perform matched filtering, and then perform segmented accumulation to obtain distance resolution which is inversely proportional to the bandwidth and the signal-to-noise ratio after the single sweep-frequency signal is compressed under the same energy condition, thereby realizing secondary compression on the multi-sweep-frequency signals. The signals generated by the method have higher spectrum utilization rate and lower interception probability, and guarantee the distance resolution and detection distance of a radar.
