MTI system simulation and clutter output statistics
Abstract
A radar return from a patch of clutter usually consists of a large number of echoes from individual scatterers. Each of these scatterers moves randomly and introduces a randomly distributed Doppler spectrum. Therefore, to simulate the performance of a MTI (Moving Target Indicator) system, we must sum a large number of randomly distributed samples from each radar pulse return. The computertime required in this case is very lengthy, and therefore it is not feasible for us to use this approach in a largescale simulation. In this report we use a simplified clutter return model for MTI simulation. We show how this model produces the same correlation function and spectral density function as the ones measured from an actual radar return. We then use this simulation program to compute the statistical distribution of the improvement factor of a MTI system with binomial weights.
