چکیده

In this study a time-frequency method based on Wigner-Ville Distribution (WVD) is used for detection and parameter estimation of Frequency Modulated Continuous Wave (FM-CW) Radar Signal. The proposed method uses the Pseudo-Wigner-Ville Distribution (PWVD) as a time-frequency detection technique and Radon Transform to identify the parameter of the modulation. The Wigner-Ville Radon Transform (WVRT) is suboptimal in detection and parameter estimation of FM-CW low probability of intercept (LPI) radar waveform. Autonomously detecting and analysing of FM-CW can eliminate the need of human intervention. It has been shown that the proposed algorithm can extract FM-CW radar modulation parameter efficiently.

Detection Performance Improvement of FMCW Radar Using Frequency Shift

Frequency modulated continuous wave (FMCW) radars have been widely used for measuring target range and speed. In this paper, we present a mathematical model that quantifies the system-level performance of FMCW radar systems. In FMCW radar, the target range is measured through measuring the beat frequency between the transmitted and received signal, usually by using Fast Fourier Transform (FFT)....
