Signal processing considerations for an application of bistatic radar

Abstract

Two classical aspects of signal processing for a monostatic radar are extended to a bistatic radar. These are the determination of target range and relative velocity when using a continuous-wave (CW) transmitter. A simple moving-target indicator using the chirp Z-transform is used to determine the velocity while reducing clutter. A digital phase detector provides the range measurement. The application discussed is the detection of a single target that has jamming capabilities. The bistatic radar has inherent advantages against such a target due to the receiver site being passive and the basic geometry of the radar system.<>
