Non-coherent Logarithmic Detector Performance in Log-Normal and Weibull Clutter Environment (UWB Automotive Application)

High range resolution ultra wideband radars attract considerable attention as short range automotive radar for target detection and ranging. Radar signal reflected from a target often contains unwanted echoes called as clutter, so the detection of target is difficult with clutter echoes. Therefore, it is important to investigate the radar detector performance for the better detection of the reflected signals. This paper analyzes the detection performance of non-coherent logarithmic detector in log normal and weibull clutter environment. The detection probability of the detector is obtained with different mean and variance value in log normal clutter environment, and with different shape parameter and scale parameter values in weibull clutter environment at different system bandwidth of 1GHz, 500MHz and 100MHz.
