Embodiment Construction
[0037] In order to better understand the technical solutions of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0038] The concrete steps of a kind of compressed sensing imaging method for synthetic aperture radar of the present invention comprise:
[0039] Step 1): The synthetic aperture radar transmits a chirp signal along the platform motion track in azimuth, and the receiving end collects the target echo and performs down-conversion and I / Q demodulation to obtain the baseband echo signal s(t a , t r ), where t a and t r represent the azimuth (slow) time and range (fast) time respectively, and the corresponding azimuth frequency and range frequency are f a and f r ;
[0040] will s(t a , t r ) discretization to get N a ×N r The matrix S, N a Indicates the number of azimuth pulses, N r Indicates the number of points in the distance direction, and the minimum...
