MTI Followed by Incoherent Integration-An Exact Analysis.

Abstract

Provides an exact computational method (and the associated theory) for determining the detection threshold to be used when a square-law integrator is applied to the output from a nonrecursive MTI. Using this method, a table of bias levels is computed for a two-pulse (single-delay) MTI for several values of the number N of pulses integrated and the probability PFA of a false alarm. Derives the characteristic function of the output of the square-law integrator when the MTI input contains a signal with Doppler frequency f sub d and amplitude G. Gives the general theory for obtaining the characteristic function of the sum of squared magnitudes of correlated, circular-Gaussian random variables. Discusses in detail the application of the general theory to the computation of bias levels for a nonrecursive MTI. Briefly considers applications to signal detection based on incoherent integration of overlapping discrete Fourier transforms. (Author)
