Embodiment Construction
[0048] refer to figure 1 , the SAR imaging processing implementation steps of the present invention are as follows:
[0049] Step 1. In the beam-pointing SAR mode, in order to avoid the complex problems caused by sub-aperture block, the original SAR echo signal is received by the full aperture in the channel mode of one transmission and multiple reception.
[0050] Step 2: Perform azimuth bandwidth compression processing and beam compression processing on the echo signal to solve the problem of excessive beam-pointing SAR azimuth bandwidth.
[0051] 2a) Construct the azimuth bandwidth compression function H′(t a , X m ) and the beam compression function H(t a , X m )for:
[0052] H ( t a , X m ) = exp ( - j 2 πα ( ...
