The Steering Problem for the Mirror-Scan Tracking System. Part 1. The Stop-Go-Stop Procedure.

Abstract

Tracking radar systems are being designed which use a lightweight mirror to steer the radar beam. Such systems can track several targets simultaneously, and the steering problem is to find the beam motion which covers a given collection of targets with minimum update time. In this report it is shown how the steering problem is a control-theoretic problem on the sphere. The suboptimal stop-go-stop solutions are discussed, and it is determined that the proposed Mirror Scan system can simultaneously track at least seven targets in a half-hemisphere with an update time of less than 1 second.
