Application of Integer Programming Genetic Algorithm in P Code Direct Acquisition Method

P code direct acquisition method has many parameters, such as averaging dot number, coherent integration time, non-coherent accumulation times, frequency steps, Tong detection parameters, FFT computing unit number and so on. In order to lower resources consumption under the constraints of detection probability, false alarm probability and acquisition time requirement, the integer programming genetic algorithm was proposed to solve the constrained multi-variable non-linear optimizing problem. The integer programming genetic algorithm, which is drawn on the idea of genetic algorithm, meets the requirements of integer value limitation. The proposed method is useful in practical application to obtain the optimal parameter values under various conditions.
