Optimization Design for Search Control Parameter of Phased Array Radar Based on RF Stealth

RF stealth technology of airborne radar has important signifi cance to improve the viability of the aircraft. The airborne phased search control parameter of array radar is designed. By analyzing th e principle of intercept probability, the relationship between target characteri stics and search performance of radar system are given, and the impact model of dwell time and beam position interval is constructed to optimize the performance under the constraints of target detection and stealth requirement. The search optimal control parameters are obtained for phased array radar to sat isfy stealth requirements.
