Abstract :
The basic function of the radar receiver is detection and ranging of a target. In receiver, various operations are carried out, to get the baseband signal for signal processing. The components in the receiver cause signal distortion and correlated noise. This paper investigates the effect of receiver bandpass filter on the received signal in radar applications. Signal is barker coded pulse, emphasis is how the signal gets distorted and its effect on the receiver performance. For baseband signal processing, continuous passband communication system is modeled as an equivalent lowpass (ELP) system. Then the autocorrelation function (ACF) invariant discrete equivalent of a continuous system is used to model the complete radar receiver in digital domain.
