What is Compound Interference Suppression for Bistatic FDA-MIMO Radar Based on Joint Two-Stage Processing about?

Frequency diverse array (FDA)-multiple-input multiple-output (MIMO) radar is characterized by extra degreesof-freedom (DOFs) in the range domain, which can be utilized in mainlobe deceptive jammer suppression. However, the jammer suppression performance degrades evidently in the presence of compound suppressive jamming signals and deceptive jammers. To this end, this paper deals with the suppression of compound interferences (including the suppressive jamming signals and deceptive jammers) in bistatic FDA-MIMO radar. At the design stage, a colocated FDA-MIMO radar is considered in node 1, while the node 2 serves as a receive-only array, which is configured as a distributed FDA-MIMO radar by combining with the transmit array in node 1. Then, a two-stage processing is performed to suppress the compound interferences, including: 1) the mainlobe maintenance processing to ensure the maximum response of the target; 2) the suppression of mainlobe interferences with joint local and global processing. At the analysis stage, the output signal-to-interference-plus-noise ratio (SINR) is analyzed, and a comparison among different radar frameworks is carried out. Numerical results demonstrate th
