Geometric Match Filter and It’s Response to Dense Fake Signal

Aiming at the anti-jamming problem of dense false signals caused by interrupted sampling repeater-jamming, the matched filter’s process was reexamined based on geometric algebra tools. The geometric matched filter was designed with the projection angle co-angle as the filter output. By comparing with the traditional matched filter under the typical parameters, the advantages of the geometric matched filter to the identification and jamming of jamming are explained. It provides a new perspective for the confrontation between radar and dense false signals.
