Rabbit ear effect is a special problem in the channelized receiver. In this paper, response mode of rabbit ear effect is examined. From the response mode, a new eliminating method based on the response estimation is proposed. The method detects the transient energy in channelized output and determines the occurrence of rabbit ear effect. Then response of the effect in each channel is estimated to...
Traditional method of estimating noise variance with signal present in channelized receiver utilizes quiet channels. Today's EM environment has high signal density and many FM signals, which disable us to find a channel being quiet long enough to obtain enough noise samples. Therefore we proposed a method based on order statistics. New subsets of noise samples are generated by sorting channelized...
In this paper, we present a method to estimate frequency rate of the Cross-Range reference signal of SAR. The method is used in the deception jamming to SAR primarily. We set up a model of pulse signal intercepted by monostatic radar receiver on the ground. With the model, a novel way is given to find out a phase sequence without phase wrapping in the case of that there is a jitter in the rising edge...
