Range-Doppler maps from simulations (input SRR =−12 dB). Maps of the a received signal, b output signal from the SSE algorithm, c output signal from the PCI algorithm, d output signal from the AR pre-whitening, and e output signal from the proposed algorithm. Each range-Doppler map is acquired using the block-normalized matched filter [9]
