Abstract: Most current radars are designed to transmit short duration pulses with relatively high peak power. These radars can be detected easily by the use of relatively modest EW intercept receivers. Three radar functions, namely search, antiship missile (ASM) seeker and navigation, are examined in this report to evaluate the effectiveness of potential low probability of intercept (LPI) techniques, such as waveform coding, antenna profile control and power management, that a radar may employ against current EW receivers. The general conclusion is that it is possible to design a LPI radar which is effective against current intercept EW receivers. LPI operation is most easily achieved at close ranges and against a target with a large radar cross section. The general system sensitivity requirement for the detection of current and projected LPI radars is found to be on the order of - 100 dBmi which cannot be met by current EW receivers. TRUNCATED
