Passive receivers can be used to detect radar emissions over considerable distances. If range resolution requirements are fixed, it is of interest to compare the detectability of equal-bandwidth/equal-energy waveforms regardless of their time duration. Relative detection ranges are predicted, via computer simulation, for two types of transmitted waveforms: a benchmark rectangular pulse and a Welti binary coded waveform. The waveforms will be detected by square-law, delay and multiply, wideband, and channelized passive receivers possessing typical bandwidth, noise-floor, and loss parameters. A comparison is given showing the relative low probability of intercept and low probability of detection (LPI/LPD) attributes of each waveform and the relative detection attributes of each receiver.
