Abstract

The optimal scheduling of track updates in phased-array radars is considered to minimize the radar energy resources required for track maintenance. The energy-optimal scheduling problem is formulated into a nonlinear optimal control problem, and a numerical procedure for its solution is presented. The scheduling problem is solved for typical examples to illustrate a pair of optimal sequences of track update intervals and signal-to-noise ratios (SNRs)
