The paper presents a method for estimation of acceleration in passive coherent location (PCL) radar. The method is based on the Generalized Chirp Transform, which is a maximum likelihood estimator in this case. The authors propose a fast and efficient algorithm for calculating acceleration by filtering a two-dimensional range-Doppler surface. The algorithm is tested on simulated data as well as on...
A continuous wave noise radar receives all the echoes simultaneously. Thus, strong echoes of nearby targets mask the weak echoes of far targets. Even if the echoes are separated in Doppler and in range, the strong echo produces relatively high sidelobes at the output of the correlation receiver. The sidelobes may prevent the detection of a weaker echo. Classical methods of strong echo removal, based...
