Example Embodiment
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings of the specification. With reference to the drawings in the specification, the processing flow of the present invention is divided into the following steps:
[0023] 1) Radar echo range pulse pressure
[0024] At the coherent radar receiving end, the radar echo data received and amplified after being amplified is sampled in the range and azimuth direction. Usually the range sampling interval is equal to the radar range resolution unit, and the azimuth sampling frequency is equal to the pulse repetition frequency to ensure In the range and azimuth signal processing time, the echo of the moving target can be collected completely, and the radar echo data in the range can be demodulated. IF (t,t m ), the radar signal can be used as the demodulation reference signal
[0025]
[0026] In the formula, t is the fast time in the pulse, t m Is the slow time between pulses, s r...
