The MIMO Surveillance Radars System with High Accuracy Finding 2D Coordinates

The paper analyses the disadvantages of an existing monostatic radar and the advantages of MIMO (Multiple Input Multiple Output) radar systems for detecting a low radar cross-section of the small-sized 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 the aircrafts. This will increase the probability of detecting the 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 the aircrafts is carried out by the mathematical modelling method.
