ABSTRACT
Figure 12.1 shows a simplified block diagram of a radar matched filter receiver followed by a threshold decision logic. The signal at the input of the matched filter is composed of the target echo signal and additive zero mean Gaussian noise (white noise is assumed in the analysis presented in this chapter) random process , with variance . The input noise is assumed to be spatially incoherent and uncorrelated with the signal. The matched filter impulse response is , and its output is denoted by the signal , which was derived in Chapter 4; it is given by
