Radar Cross Section Inversion in Sparse Sampling Mode using Compressed Sensing Techniques

The traditional RCS test system needs to meet the Nyquist sampling criterion. It puts great pressure on the data processing and storage capacity of RCS test system in large test tasks. In this paper, a new RCS test system is studied. By using compressed sensing technology, the accurate measurement of RCS can be realized in the undersampling mode. By designing comparative experiments, when the compression ratio is 0.5, the CS-RCS test technology has a measurement accuracy error within 0.2dB compared with the traditional RCS test technology, and only half of the data is used.
