RADIATING OR ILLUMINATED BY THE EXTERNAL RADIO-ELECTRONIC MEANS TARGET PATH TRACKING METHOD (EMBODIMENTS) AND RADAR LOCATION SYSTEM FOR ITS IMPLEMENTATION (EMBODIMENTS) Russian patent published in 2018 - IPC G01S13/66 

FIELD: radar ranging and radio navigation.

SUBSTANCE: inventions relate to the field of radar ranging and can be used in the systems consisting of radar location modules (RLM): radar ranging stations or radar ranging transceiver modules. By the first embodiment of the method the technical result is achieved by the fact, that in the radiating target path tracking method, based on its direction finding location from the spatially spaced points by the radiations (reflections) and on the range to the target calculation, the target direction finding is performed with the help of included into the radar location system (RLS) two or more RLMs, at that, the RLMs are exchanging the bearing change graphs parameters in the universal time, based on the graphs parameters extrapolation calculating the predicted ranges, producing tracking gates along the bearings and range, and after the target path detection in the active mode conducting its tracking in the passive mode. According to the method second embodiment, the said technical result is achieved by the fact, that in the radiating target path tracking method, based on its direction finding location from the spatially spaced points by the radiations (reflections) and on the range to the target calculation, target direction finding is performed by means of included into the RLS two or more RLMs, which also includes the processing module (PM), at that in the PM, on the basis of received in the RLS bearings data extrapolation, calculating the predicted ranges, producing the tracking gates by bearings and range, and after the target path detection in the active mode conducting its tracking in the passive mode. Method first embodiment is implemented by the radiating target path tracking system, consisting of two and more spaced apart RLMs and PMs, the RLM inputs / outputs are connected to the PM outputs / inputs, and the PM output is the RLS output, into the RLM target direction finders are introduced, each of the RLM target direction information inputs / outputs are mutually connected to the inputs / outputs. Method second embodiment is implemented by the radiating target path tracking radar location system, consisting of two or more spaced apart RLMs and PMs, the RLM inputs / outputs are connected to the PM outputs / inputs, and the PM output is the RLS output, in the RLM target direction finders are included, or one of them is included in the PM, the RLM target bearings information outputs are connected to the PM inputs.

EFFECT: reduction in the RLM active mode using time with the radiating or illuminated by the external radioelectronic means (hereafter is the radiating) target path independent tracking and exclusion of the false targets.
