Paper Abstract

In this paper, we present an approach to improve weak signal detection in a non-Gaussian environment. This solution is developed under the assumption that the interference is described by a spherically invariant random process. As such, the weak signal detector reduces to a conventional correlator, modulated by a zero-memory nonlinearity prior to threshold processing. This receiver is designed for operation in those regions of the angle- Doppler space where target returns and interference are coincident, and not separable through conventional space-timing filtering.
