STUDY AND EXPERIMENTAL PROGRAM OPDAR TRAJECTORY MEASUREMENT SYSTEM.

Abstract

A CW optical radar (OPDAR) for precise early launch phase trajectory measurement is described. A single instrument measures slant range, azimuth and elevation to a small, passive retroreflector mounted on the missile. The data collected is suitable for real-time trajectory evaluation and for post flight computer processing to yield highly precise position, velocity, and acceleration information. Laboratory models of critical components were constructed to demonstrate system feasibility. Models included a shaft angle encoder, a retroreflector, and a model of the range measurement system. An experiment was conducted to measure the effects of laser noise. (Author)
