Abstract:
We develop a structure of the multi-channel Doppler filter for processing randomly spaced bursts and analyze its efficiency. The algorithm avoids losses of several dB in processing of nonequidistant signals and allows estimating the amount of additional computation required by the modified algorithm in comparison with the classical filtering algorithm based on fast Fourier transform.
