Matched filter for radar utilizing spin-echo techniques

摘要

A matched filter for providing correlation between an RF coded radar pulse and the target return signal by means of a plurality of spin-echo elements which are sequentially range gated "on" for a time substantially equal to the radar pulse length during the target signal return time after having been "set" during the radar pulse transmission time so that the noise occurring within the RF signal bandwidth is incident during one but not more than two consecutive range gate time periods with the resulting effect that noise is reduced to the point where it has the same effect as it does upon conventional matched filters utilized for radar applications.
