The passive coherent location (PCL) radar detects potential targets by computing the cross ambiguity function (CAF) between the target echo signal and the direct path wave, which is regarded as the reference signal received from the reference channel. However, a number of the multipath interferences present in the reference signal in most cases. The existence of the multipath interferences can increase...
In this paper, an improved variable step-size NLMS algorithm is proposed, which variable step-size scheme is designed by a Versiera function. The update of the step-size is subtly sensitive to the system noise due to employ the system input power and cross-correlation between the input signal and estimated error. Moreover, the proposed algorithm is stable. Simulation results for system identification...
