Abstract

Abstract

Rotating phased array multi-function radar have electronically scanning capability both in elevation and in azimuth. It can allocate time and energy both in azimuth and elevation more flexible than the mechanical scanning radar. In order to optimize the effects of search, it is needed to divide and assess the areas. Based on the calculation of the most threatening path of the rotating phased array radar, this paper presents a novel method of regional threat level assessment; The radar problem of most threatening trajectories computation may be declined to a shortest path problem solved by calculus of variations by taking the detection probability as the price function; The shortest path computation based on Eikonal equations are solved with the fast marching method. The most threatening path are computed by backtracking the minimal path based on steepest gradient descent method. Finally, the solution of rotating phased array multi-function radar resources management is proposed based on divided areas, and the validity of the technique is checked and rationality of constructed model is verified by providing instances with 240 typical targets.
