Abstract: A new improved optimization method is promoted based on common minimum-maximum principle for implementation of the filter bank of MTD radar. This new method has clearly physical signification, which is to minimize the output power of the clutter. In this way, it can change the optimization function to a minimal function. It reduces the complexity of solution the optimization problem. In this paper, the steepest descent arithmetic is used. The computer simulations results show that it is approximate to the common ones. The new method is a viable way in engineering applications.
