Abstract

The paper describes application of optics-geometrical method in short-range optical radar for measuring reflection characteristics of target and radiator’s angular energy distribution. The possibility of signal sampling in a base-type optical radar device using multi-element photoreceiver is studied as well as ways of improving precision of measurements with respect to linear coordinate up to ~1 mm.

A ratio between reflection coefficient of target’s surface and image coordinate in photoreceiver’s plane is determined. A working equation for calculating radiation pattern of radiator using the method of self-scanning of photoreceiver’s field of view with respect to its flare with precision ±0.5° with respect to angle coordinate is obtained.
