GENERAL PROBLEMS OF METROLOGY AND MEASUREMENT TECHNIQUE: METHOD OF CONSTRUCTING A TWO-DIMENSIONAL IMAGE OF AN AIR TARGET WITH AN ARBITRARY UNSTABLE FLIGHT TRAJECTORY

摘要

The principle is described of forming a two-dimensional radar image of an air target when using multifrequency narrow band pulsed probing. The ways of converting signals reflected from a target executing an unstable flight in a turbulent atmosphere are indicated using an analytical method. New algorithms are proposed for adapting the method to the conditions of the trajectory instabilities. A mathematical modeling is performed confirming the efficiency of a new method for constructing a two-dimensional image of an air target.
