Ambiguity Function Analysis for Bistatic Radar.

Abstract : The ambiguity function and its plot provide a qualitative assessment of the suitability of different radar signalling waveforms. The concept of the ambiguity function for bistatic radar is investigated in this report. The manner in which the bistatic geometry affects the ambiguity function is derived. A number of illustrative examples are provided to show the effects. The concept of the ambiguity function based on sampled signals is investigated. Expressions for both continuous time-continuous frequency and discrete time-discrete frequency ambiguity functions are derived and relationships between them are established. Sampling rates to avoid aliasing are also determined. A signal model for non-cooperative bistatic radar is presented.
