A Technique for Improving the Clutter Performance of Coherent Pulse Train Signals

Sets of Waveform and Mismatched Filter Pairs for Clutter Suppression in Marine Radar Application

“…In this example N=M=3, P=2 signal-to-noise ratio loses [5] =0,5. But if we increase memory of filter N=3, M=5 we get  =0,7 [14].…”

“…The quality of such extraction significantly depends from rangevelocity distribution of interfering reflections [1,2,3]. The problem of the mismatched filter and waveform design that maximizes the signal-to-noise-plus-clutter ratio at the receiver filter output has been formulated and addressed in [4], [5], [6], [7], [8], [9], [10], [11].…”

A max-min design of transmit sequence and receive filter

“…As to the rank of W ⋆ , a similar observation was made for most of the employed random starting points. Nevertheless, by setting Ω = [1,2], Ω c = [−0.25, 0.25], δ 0 = 0.1, we find a case for which we have rank(W ⋆ ) = 2 and rank(X ⋆ ) = 1. The SINR associated with the optimal solutions and the employed rank-one decomposition method are illustrated in Fig.…”

“…We investigate the robustness of the system SINR w.r.t target Doppler shift assuming Ω = [ν l , ν u ] = [1,3] and…”

“…Most of the works have been concerned with either stationary targets or targets with known Doppler shifts (see e.g. [1][2][3][4][5]). In [6], considering a stationary target, a frequency domain approach has been employed to obtain an optimal receive filter and corresponding optimal energy spectral density of the transmit signal; then a synthesis procedure has been used to approximately provide the time domain signal.…”
