Abstract

Abstract

Spread Doppler Clutter (SDC) caused by multi-mode propagation restrains the detection performance of Over-The-Horizon Radar (OTHR) for low detectable targets, such as slow ships. To solve this problem, a bi-iterative Minimum Variance Distortionless Response (MVDR) beamformer is proposed to suppress multi-mode SDC for MIMO OTHR system. As it is difficult to obtain the signal-free training data and enough sample support in MIMO-OTHR with time-staggered linear frequency modulated continuous wave or slow time phase-coded waveforms, the block matrix is used for data preprocessing to reduce the effect of expected signal component in the training data, then multi-mode SDC could be suppressed by the LN-variate MVDR beamformer which is restored through bi-iterative calculation with an L-variate transmit and an N-variate receive beamformer. This algorithm improves the convergence of MVDR beamformer, while reducing the computational load and the requirement of sample support. Theoretical analysis and simulation experiment are presented to verify the effectiveness of this algorithm.
