Abstract
In order to mitigate the Range-Doppler ambiguities inherent in a sparse aperture, high pulse repetition frequency is adopted to resolve Doppler ambiguous and waveform approach exploits temporal diversity to resolve range ambiguities. In this paper, a novel GA with gradient-like reproduce is presented to optimize multiple bi-phase encoded waveforms, so their peak side-lobe and integrated side-lobe of auto-correlation and cross-correlation are all as lower as possible. The fitness function with adaptive scale gene corresponding to multiple constraint is used to overcome optimal trend. The simulation results are presented to show the performance and behavior of the algorithm proposed.
