Abstract

Based on analysis of the signal characteristic of the reference channel and the target echo channel for passive radar

we derive the relations of the coherent accumulation gain formula

the signal-to-noise ratio (SNR) of the reference channel

the effective bandwidth of the signal and the coherent accumulation time

which provides the theoretical base for predicting the detection performance of passive radar.Moreover

some suggestions for the baseline selection of passive radar are presented after the relations between the coherent accumulation gain and the SNR of the reference channel are verified and analyzed.
