An Accurate Sparse Recovery Algorithm for Range-Angle Localization of Targets via Double-Pulse FDA-MIMO Radar

Algorithm 1: An accurate sparse recovery algorithm for double-pulse FDA-MIMO radar.

(1) The FDA-MIMO radar transmits a pulse with a zero frequency increment to obtain the received signal

(2) The sparse vector is obtained by CVX optimization of (15). Angle estimates are realized by searching maximum values through a one-dimensional spectrum of

(3) Use the method in subsection to optimize the angle estimates in step 2. Then, the refined angle estimates can be received as
