Modelling sea clutter temporal correlation in detection calculations

The calculation of target detection performance in a combination of K-distributed sea clutter and radar system noise has, to date, been limited to the case where the clutter speckle component is independent from pulse to pulse (as sometimes occurs with frequency agility). Recent advances in computational techniques reported here allow the speckle and noise to have different correlation times, thereby allowing fixed frequency and limited frequency agility radars to be modelled at all ranges and at all clutter to noise ratios.
