Optimal design for MTI stagger code based on ant colony algorithm

The optimal design method for moving target indication(MTI)stagger code based on ant colony algorithm(ACA)is presented.Under the conditions that the maximum stagger ratio is less than or equal to the allowed value and the expansion multiple of blind speed is greater than that corresponding to the first blind speed,the ACA is used to search the optimal stagger code which makes the first notch depth of the stagger MTI filter as shallow as possible and the pass-band as flat as possible,so the target loss decreases when the clutter is supressed.The MTI stagger code design is a kind of combinatorial optimization problem,and the ACA is very suitable for solving this kind of problem.The provided design examples and performance analysis demonstrate the feasibility and validity of the design method.
