Abstract

Frequency and phase combined modulation waveform has been considered as an important technology that provides significantly improved LPI performance and compression ratio in Radar system. In this paper, genetic simulated annealing algorithm(GASA) has been applied to the design and optimization of the combined modulation waveform. On the basis of genetic algorithm(GA), GASA introduces annealing process in energetic, thus enhancing the searching capability and efficiency in the whole searching scope. The feasibility and high efficiency of the algorithm is validated by the simulation result and implementation in engineering.
