| Abstract | ||||
| This paper introduces the application of Wigner- Ville Distribution (WVD) in LFMCW radar systems to perform the range-Doppler processing of targets instead of FFT processing. The proposed approach enhances the detection capability of the LFMCW radar based on the fact that the side lobe levels (SLLs) in WVD spectrum are very small in magnitude, this fact facilities the realization of LFMCW radar by WVD without the need of additional weighting to reduce SLL in FFT-based approach. Computer simulation via Monte Carlo trials is provided to evaluate the performance of the proposed WVD-based LFMCW radar compared to that of the FFT-based one. The Receiver Operating Characteristics (ROC) is used as the performance measure. Simulation results validate the superiority of the proposed approach. | ||||
