Embodiment Construction
[0051] The content of the invention of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0052] Such as figure 1 As shown, the pulse compression method used in the frequency domain of the chirp signal provided by this embodiment includes the following steps:
[0053] S1: Perform quadrature demodulation on the chirp signal in the time domain;
[0054] S2: performing low-pass filtering on the chirp signal in the time domain after quadrature demodulation;
[0055] S3: sequentially performing Fourier transform and frequency band shifting on the low-pass filtered chirp signal in the time domain to obtain the chirp signal in the frequency domain;
[0056] S4: sequentially perform Fourier transform and frequency band shift on the matched filter signal in the time domain to obtain the matched filter signal in the frequency domain;
[0057] S5: performing complex conjugate multiplication of the chirp signal in the ...
