Abstract: In the present work, a sinusoidal detection method based on Wigner–Ville distribution (WVD) proposed in [1] is applied in the Moving Target Detection (MTD) for realizing a bank of Doppler filters instead of the direct Fast Fourier Transform (FFT) or WVD in a typical ground based radar. The proposed MTD scheme does not suffer from cross terms produced due to the bilinear nature of WVD. It enhances the target detection capabilities by providing higher detection probabilities and additional gain of 9 and 11 dB in the improvement factor, in the presence of ground and weather clutter, compared to WVD and direct FFT schemes respectively. Performance of the proposed MTD scheme and the other mentioned schemes is evaluated through computer simulation by generating receiver operating characteristics (ROCs) via Monte Carlo trials.
