TL;DR: In this article, the authors proposed a parallel tracking method for the detection of separated and resolved guided air-to-air (A2A) guided missiles, which involves parallel tracking based on a procedure with optimum multidimensional linear discrete Kalman filtration of a MANET.

TL;DR: In this paper, a parallel maintenaning based on Kalman filtering is proposed to identify impacts or absence of the interference leading away by rate based on the calculation of the derivative difference modules between the Doppler frequency samples (DF) caused by the signal reflections from the group airframes and the centroid DF samples caused by signals from the impeller blades of the first compressor stage of the low pressure group aircraft engines.

Abstract: FIELD: radar ranging and radio navigation.SUBSTANCE: invention relates to radar ranging and can be used to expand functional capabilities of pulse-Doppler on-board radar station (BRS). Method consists in scanning the space with the main beam of the beam pattern of the antenna (BPA) with the compensation channel on the side lobes when the aerial target (AT) is detected by means of the pulse-Doppler BRS, setting the gain in the main channel smaller and commensurate with the signal gain in the compensation channel, converting the signals in the main and compensation channels into corresponding amplitude-frequency spectra, at that, when the AT is irradiated of the pulse-Doppler radar BRS BPA main beam amplitudes Aand Aspectral components of the signal in the main and compensation channels, respectively, are located at the frequency position f, caused by Doppler shift of carrier frequency of BRS due to mutual movement of its carrier and irradiated AT, when the production aircraft is irradiated to noise of DRFM type – digital radio-frequency memory equipped with a radio reconnaissance station (RRS), main beam BPA of pulse-Doppler BRS amplitudes Aand Aspectral components of the signal in the main and compensation channels, respectively, are located at the frequency position f, caused by Doppler shift of carrier frequency of BRS due to mutual movement of its carrier and irradiated aircraft-producer of noise type DRFM, when the AT is irradiated to the main beam of the BPA and the jamming by the aircraft-producer is hitting the sighting point on the frequency position fpreviously explored using the RRS, type DRFM interference on BPA side lobes of amplitudes Aand Aspectral components of the signal in the main and compensation channels, respectively, are located at the frequency position f, amplitudes Aand Aspectral components of the interference signal in the main and compensation channels, respectively, are located at the frequency position f, analysis of the spectral components of the signal and their amplitudes is carried out, depending on the result, only the useful BRS signal is processed or the useful BRS signal is processed in the radar antenna with simultaneous rejection of the DRFM type interference at the frequency position f.EFFECT: broader functional capabilities of the BRS due to recognition of the action on the side lobes of the BPA from the outermost point of the space of the frequency-targeted noise of the DRFM type when detecting the AT, covered by the noise producer aircraft, and, in case of its effect, treatment of useful signal in BRS with simultaneous rejection of DRFM type interference.1 cl, 3 dwg
