Abstract :
A set of theoretical techniques to prevent a radar from being used by a bistatic radar receiver as a non-cooperative illuminator are analysed. This orks by radiating in additio to the radar signal aveform, a ´masking signal´ aveform hich is orthogonal to the radar signal aveform, both i the coding domai and the spatial domain. A number of different coding schemes are analysed. T o spatial coding methods are presented and analysed: the first uses a pair of interferometer elements at the extremities of the radar antenna array; the second uses a Butler matrix to generate a set of orthogonal beams. System-level calculations are presented to sho the level of masking of the radar signal received by a bistatic radar receiver, and the suppressio of the masking signal i the host radar echo. Some ideas for further ork are presented.
