Research on synthesis of symmetrical thinned linear arrays

For the synthesis of the symmetrical sparse linear arrays with some thinned rate, only taking some elements rounds the end of the aperture into account will have the same effect on the peak side lobe level with taking all the elements into account. Using statistical method, the distribution characteristic of elements of many optimum thinned arrays are studied in this paper firstly, then a aperture release model is presented to synthesize the symmetrical thinned arrays, this model can reduce the computing burden and improve the efficiency in the optimization without expense of performance. Finally, some test and analysis to testify the advantages are presented.
