Low probability of intercept radar
Abstract
The objective of LPI radars is defined and performance characteristics are examined. A performance criterion relating the range at which the LPI radar can detect a target to the range at which an intercept receiver aboard the target can detect the LPI radar is defined. The response of various operational and advanced intercept receivers to wideband LPI radar waveforms is explored. The performance criterion is evaluated as a function of the LPI radars time-bandwidth product and sidelobe response (both ordinary and ultralow) for a number of operational and advanced intercept receivers. An ambiguity diagram that provides the response of the intercept receiver to the LPI waveform for mismatches in receiver time and frequency response is described. The ambiguity diagram is evaluated for various mismatched receivers. A processor is discussed that improves the response of intercept receivers to pulse compression radar waveforms.
