PROJECT TITLE :

Optimal rabbit ear detection and suppression for electronic support receiver

ABSTRACT:

Any channelized receiver suffers from a phenomenon called the rabbit ear result. This phenomenon seems when an out-of-band pulse generates a distorted response at the output of the chosen filter. In this paper, the rabbit ear impact is analyzed, and a triband filter structure is proposed to spot and suppress the rabbit ear result. The average likelihood detection strategy is adopted to optimize the parameters of the triband filter, additionally as the detector structure. It's shown that although competing methods reject all short-duration pulses, the proposed system preserves all in-band pulses, whereas eliminating most of the out-of-band pulses (i.e., rabbit ear pulses).
