Abstract

Wideband radar jamming system has a high demand on A/D devices. In this paper, a high speed sampling technology based on “multichannel and series to parallel pipeline” is proposed to solve the problem of low resolution of A/D devices under high sampling rate. The technology uses switched filter banks to divide the wideband radar signal into multiple signals in the frequency domain and the serial to parallel conversion of each signal is processed. In this way, the A/D converter allows more bits to be used in the low rate condition, thus reducing the rate of the jamming signal false component and the memory clock control signal. It can effectively improve the jamming efficiency of wideband radar.

Key words： high-speed sampling; series to parallel structure; wideband radar; jamming
