[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0036] Reference figure 1 According to the implementation flowchart in the present invention, the moving target detection method based on pulse compression frequency agile radar specifically includes the following steps:
[0037] S1. Band-pass sampling of the echo signal received by the pulse compression frequency agile radar, the bandwidth covers the frequency agility range of the echo signal; to ensure that the sampled signal is not distorted, the sampling rate should be greater than or equal to twice the frequency agility of the echo signal Variable range, namely f s ≥2·max(b n f Δ ), where f s Indicates the sampling rate;
[0038] S2. De-initial carrier frequency processing is performed on the echo signal r(t) after band-pass sampling in step S1, that is, the initial carrier frequency f in the echo signal is eliminated 0 And retain the agile frequency b of ea...
