The primary unique criterion for stealth waveform design is reasonably flat, total operating frequency band coverage. This objective isn't always compatible with best data link or radar mode performance. Some obvious criteria are stated in this section. These criteria are then applied to various spread spectrum strategies such as frequency diversity, discrete phase codes, linear FM, and hybrid waveforms. LPI requirements, in addition to SNR considerations, dictate the use of high duty cycle waveforms. This result has two implications: (1) That the transmitted pulse period must be incrementally variable and (2) that large expansion/compression ratios usually are involved.
