Mainlobe Deceptive Jammer Suppression with MIMO Radar using Element-Pulse Coding

This paper deals with the suppression of mainlobe deceptive jammers in a collocated multiple-input multiple-output (MIMO) radar by element-pulse coding (EPC). At the design stage, by simultaneously coding both spatial elements and slow time pulses, the EPC scheme has the capability of discriminating the true target from the false ones, corresponding to different range ambiguity regions. In such a way, by designing an appropriate coding coefficient, the false targets, from unwanted range ambiguous regions, can be suppressed by nulling at the equivalent transmit beampattern of the true target. At the analysis stage, a detection performance comparison is implemented among the proposed scheme and traditional radar frameworks. Numerical simulations are carried out to corroborate the theoretical developments.
