基于无人机的双基地低成本 SAR 系统附 MATLAB代码+仿真结果和运行方法.zip

# UAV Bistatic SAR uav-bistatic-sar is the MATLAB repository for the PoliMi project of a demonstrator for a UAV-based bistatic low cost SAR system. ## Requirements MATLAB with installed Phased Array System Toolbox and Parallel Computing Toolbox. The current version of TDBP focusing implements `gpuArray` and it s being developed a version using CUDA acceleration. ## Folders explanation ### SDR_scripts Scripts used to run the SDR board for acquisition of the data. The most important files are inside `gnuradio` and are used to start transmission and reception of samples. ### lib Functions often needed in the other scripts, mainly for storing and loading binary complex data in an interleaved format. ### mat_files Here should be copied the dataset to be downloaded independently. ### range compression Scripts needed to perform the FFT based range compression on the raw binary data collected by the SDR. ### tx_waveforms Waveforms transmitted in the various experiment, in different formats. ### uav processing Main script used to elaborate the RangeCompressed data. First it is time and phase corrected using navigation data, then it is focused with TDBP algorithm on a specified grid.
