Abstract :
A low probability of intercept signal detectability analysis (LPI/SDA) program which calculates the detectability of certain spread-spectrum signals by radiometric detection systems is described. LPI/SDA is a PC-based computer aided analysis system which expresses the detectability of a signal in terms of the signal carrier power to one-sided noise power spectral density required at the input to a radiometer to achieve user-specified detection and false alarm probabilities. LPI/SDA also has the ability to calculate LPI system quality factors, which describe the detectability of a signal separately in terms of scenario-dependent and scenario-independent factors. Sample detectability calculations are illustrated, and performance curves are provided
