The ability to create a metrication equation of LPI performance based on input parameters is certainly feasible, as has been demonstrated here. The main obstacle to confront is the identification of what LPI is and the situational parameters in which it will be used, including system purpose and ESM receiver type. This study considers the following LPI waveforms: Linear Frequency Modulation (LFM), Sinusoidal Frequency Modulation (Sin FM), Poly-Phase Shift Keying (PPSK) techniques including Frank, P1, P2, P3, and P4 codes Costas code Frequency Shift Keying (FSK), and Costas-Barker Hybrid (FSK/PSK). This work represents the first attempt to be published in the open literature to quantify the LPI properties of transmitted radar waveforms. Secure waveform coding strategies to minimize the risk of divulging radar capabilities is known as low probability of exploitation (LPE) and is not considered here.
