The Method of the High Accuracy Finding 2D Coordinates in MIMO-radar Based on Existing Surveillance Radars

Abstract

The paper The work analyses the disadvantages of an existing monostatic radar and the advantages of MIMO radar systems in detecting a low radar cross-section of the smallsized aircraft. It was proposed to use several existing unidirectional surveillance radars as elements of a small base synchronous MIMO-radar system in order to improve the quality of detection air-crafts. This will increase the probability of detecting small-sized aircraft by exposing them to different angles of spatially spaced radars and using the property of the dependence of aircrafts radar cross-section on the direction of irradiation. In addition the MIMO-radar it is possible to improve the accuracy of the finding 2D coordinates while to surveillance the airspace. The calculation of the quality parameters of detection air-crafts is carried out by the method of mathematical model.
