The Classical MUSIC algorithm points out that in order to distinguish N waves from different directions,an N element array is needed. Therefore, in order to distinguish multi-detect signal simultaneously, an array is needed ,the payload of satellite and reconnaissance aircraft platform is limited , large array antenna can’t be placed, and application of MUSIC algorithm is restricted on these platform. In this paper a MUSIC algorithm with single antenna is proposed using movement of single antenna, the resource-demanding disadvantage of classical is improved.This algorithm can be used on resource limit satellite and aircraft platform.This algorithm is verified efficacious in the paper by simulation.

In this paper, a novel hybrid Invasive Weed Optimization (IWO) and Cuckoo Search (CS) algorithm (IWO/CS) is presented for phase-only pattern synthesis of large array antenna. The hybrid IWO/CS algorithm embeds the Levy flight of CS algorithm into IWO algorithm as a global guide, thereby enhancing the global search ability of the algorithm. At the same time, in order to avoid trapping into the local optimal solution, mutation operator is introduced to enhance search ability of the algorithm. Finally, competitive exclusion operation is improved to maintain the diversity of population. The hybrid algorithm is applied to phase-only beam shaping to achieve main lobe broadening and side lobe depression. Simulation results demonstrate the superiority of the hybrid IWO and CS algorithm.
