Digital System of Asynchronous Pulse Noise Cancellation

V.A. Chasovsky
M.P. Chernoborodov

ABSTRACT

An algorithm is considered for the processing of the radar information coming to the input of a coherent pulse radar. The algorithm allows to detect and to cancel an asynchronous pulse noise (APN) by the processing of one range-bin. The algorithm is based on the use of the Doppler phase filters formed on the basis of the coefficients of the discrete Fourier transform. The results are presented of the mathematical simulation of the input signal processing of a digital system for the APN cancellation, the system being based on the spectral analysis of the APN characteristics. Several variants of the cancellation system are proposed.
