METHOD OF CLUSTERED AIR TARGET IDENTIFICATION Russian patent published in 2017 - IPC G01S13/52 

FIELD: radio engineering, communication.

SUBSTANCE: in the direction of detected air target, several bursts of unmodulated probing signal pulses are emitted, signals, reflected from observed air target (AT), are received, threshold value of received signal estimated parameter is set in the comparator, phase shifters are rearranged to a certain phase change sample, introduced into the probing signal, several bursts of pulses of probe signal with phase manipulation are emitted in the direction of the observed air target, reflected from observed air target (AT) signals are received, value of received signal estimated parameter is calculated, the calculated value of received signal estimated parameter of is compared with the previously established threshold value of the estimated parameter, the decision is made about the presence in the composition of the observed air targets of one or two objects. To make a decision on the identification of clustered air target, the threshold value of estimated parameter is introduced based on certain conditions, which allows to identify clustered air targets located in one resolving volume of the airborne radar (ABR), that is, to recognize the number of objects in the previously detected AT in the case, when the elements of such target are in one resolved volume of ABR, and the reflected signal has a significantly larger amplitude value than when reflected from a single AT, more than one of phase angle values introduced into the probe signal. Incorrect assessment of tactical situation, which consists in making a wrong decision about identifying the clustered air target, is excluded.

EFFECT: increasing the reliability of information received to decide on the identification of clustered air target at the target detection stage by means of an airborne radar in the case where the elements of such target are in one resolved volume of airborne radar.
