RADAR TARGET TRACKING METHOD (VERSIONS) Russian patent published in 2011 - IPC G01S13/02 

FIELD: physics.

SUBSTANCE: according to the first version of the invention, a decision is made on target detection if the level of the received signal reaches a detection threshold set based on the acceptable false alarm level. A tracking strobe on that signal is formed and then taken for tracking through its allocated tracking channel. Further, after receiving signals from the i-th angular direction, n signals with the highest weight which have not reached the threshold detection are taken for preliminary tracking while accommodating free tracking channels. After receiving signals from the (i+1)-th angular direction when detecting k new targets, k signals of the i-th angular direction with the least weight are discarded with preliminary tracking, as well as m more signals with less weight than m signals of the (i+1)-th angular direction which have not reached threshold detection. k signals of the (i+1)-th angular direction are taken for preliminary tracking and (n-k) signals of the i-th and (i-1)-th angular directions with the highest weight which have not reached threshold detection undergo preliminary tracking, and are then discarded with preliminary tracking if there is need to free the tracking channel for targets detected once more or high-weight signals. According to the second version, a decision is made on signal detection if the level of the received signal has reached the detection threshold, established based on the acceptable false alarm level. A tracking strobe is formed on that signal and then taken tracking with its allocated tracking channel. Further, a strobe for tracking signals which have not reached detection threshold is created, and then discarded with preliminary tracking if there is need to free the tracking channel for targets detected once more. During each signal reception, the probability of false alarm is calculated in each preliminary tracking strobe and when it drops to the acceptable level, a decision is made on target detection in that strobe, which is transferred to the tracking strobe.

EFFECT: long range for tying target route and detection range thereof.
