Missile Guidance: Interferometer Homing Using Body-Fixed Antennas
Abstract
Six chapters comprise this document, which is a discussion of the history and technical development of homing guidance via signals from body-fixed interferometer antennas as it is used in a tactical surface-to-air missile. Chapter 1 provides an introduction and background; Chapter 2 reviews homing guidance, giving brief consideration to the guidance technique and the concept of body-motion decoupling from the interferometer signal, as well as to the attractive features and critical factors that are characteristic of interferometers; Chapter 3 deals with early developments in interfermeter guidance; Chapter 4 presents angle-measurement techniques along with their characteristic ambiguities and the methods for resolving them, describes instrumentation techniques for phase measurement by both scanning and nonscanning systems, and discusses the effects of glint noise and multiple targets; Chapter 5 describes the methods used to decouple body motion from the interferometer signal, the effects of a nonrigid airframe, and the types of measuring instruments and their tolerances; and Chapter 6 considers the use of homing guidance for current and future missiles, its compatibility with other guidance modes for a multimode missile, and its low-frequency capability and suitability for guided projectiles. This last chapter is also directed toward the modern implementation of interferometer homing using strapdown inertial instruments and digital processing.
