摘要
Abstract
Low side-lobe is an important index for phase array radar.Limited to hardware,antenna fails to do amplitude weighting while transmitting.To implement a universal low side-lobe method for both transmitting and receiving,sparse arrays or phase weighting is feasible.In view of the above,a low side-lobe design with phase weighting in simulated sparse arrays is proposed.The theoretical basis of phase weighting is given.The low side-lobe effects of phase-only weighting method and sparse arrays based on the genetic algorithm is given.And then,the theoretical formulas and simulation results of a phase weighting method for simulating sparse arrays are designed.Finally,an optimum low side-lobe result is obtained based on the combined method.The measured value by the instrument is similar to the simulation result.关键词
