Small moving target indication based on linear-variant-coefficient-difference-equation

摘要

The movement model of target limited by Track-Before-Detect (TBD) approaches is extended to that of target with constant acceleration in this paper. And an algorithm based on Linear-Vanant-Coefficient-Difference-Equation for moving target indication is proposed. Moreover, based on parametric models of target and background, this paper presents an analysis of its optimal SNR gain versus target and background characteristics as well as the sensitivity of this gain to mismatch.
