Abstract :
In this paper, clutter suppression and target detection in clutter edge is discussed. Firstly the statistical model of the clutter edge is established, based on which maximum likelihood estimation for the transition range bin of the clutter edge is derived. Simulations illustrate that by carefully choosing the secondary samples based on the estimation result of the transition range bin, the signal to inference plus noise ratio (SINR) can be improved significantly.
