LPI Radar Signal Design Resistant to Identification by ESM Systems

IEEE Transactions on Aerospace and Electronic Systems, 2023
We consider the design of a low probability of intercept (LPI) radar signal that is resistant to identification by an electronic support measure (ESM) system. We assume that the ESM attempts to distinguish between radar signal types in a finite set.
