Studying the exactitucle of digital matching filtration of widepass location signals

The resolution of matching digital filtration of wide pass location signals in time domain is studied in this work. The advantages of this kind of processing in comparison to the processing on fast convolutions in frequency domain are demonstrated. A choice of parameters of the long and short chirp signals and smoothing window have been studied to increase the ratio of the main lobe to side lobes of convolutions. This choice has carried out with the use of computer simulation and result has shown in this paper.
