Simple Analytic Approximation for Non-Coherent Radar Detection with Partially Correlated Target RCS and Compound Sea Clutter

We revisit the problem of non-coherent pulse integration in the presence of partially correlated target radar cross-section and clutter, recasting the formulae of Kanter and Weiner to forms that are more transparent and numerically stable. Generalization to compound sea clutter is considered, and an analytic approximation that can cater for a large number of integrated pulses is derived which is simple, explicit and computationally efficient, making it suitable for use in operational simulations of airborne maritime surveillance.
