Embodiment Construction
[0085] The present invention mainly adopts the mode of simulation experiment to verify the feasibility of the system model, and all steps and conclusions are verified correctly on MATLAB7.0. The specific implementation steps are as follows:
[0086] Step 1: Setting of system parameters
[0087] The system parameters adopted in this specific implementation mode are detailed in Figure 4 .
[0088] Step 2: Perform distance compression on the raw data of linear array 3D imaging synthetic aperture radar
[0089] Using the traditional SAR standard range compression method to process the SAR range echo data Compress to obtain the linear array three-dimensional imaging synthetic aperture radar data after distance compression, denoted as Linear Array 3D Imaging Synthetic Aperture Radar Data after Range Compression is a three-dimensional array, including distance dimension, along-track dimension, and cut-track dimension;
[0090] Step 3. Obtain the first range slice of the lin...
