261 | Tracking radar device | JP4628381 | 1981-03-31 | JPS57161574A | 1982-10-05 | ISHIMARU TADASHI; WATANABE SEINI; ONOKI MAKOTO |
PURPOSE:To prevent the tracking of the image under a horizontal plane and the tracking of clutters by controlling an antenna in accordance with the movement information of the target position obtained during normal tracking. CONSTITUTION:When the radar device tracks an image while tracking at a low altitude, an antenna 1 directs downward, and the difference between the smoothing depression and elevation angle signal E* which was under reproduction and calculation by a computer 9 in accordance with the movement of the target till then and the current antenna depression and elevation angle signal E increases. Hence it is compared in a comparator 11' in an input switch 10' and when said difference exceeds the predetermined value, a relay 12' is changed over to feed the differential signal epsilonE=E-E* between the smoothing depression and elevation angle signal and the antenna depression and elevation angle signal to an antenna controlling mechanism 5' so that the tracking is continued on the premise that the target flies at the speed and course before the changing over. Thereby, the antenna 1 is prevented from tracking the image appearing under the horizontal plane. | ||||||

PURPOSE:To improve the performance for separation of crossing of plural targets, by using signal intensity besides position information to track targets correlatively. CONSTITUTION:A range R1, an azimuth theta1, and a signal intensity S1 detected by a radar receiver are stored temporarily in a buffer 1. Target data R1, theta1, and S1 stored in the buffer 1 are compared with tracking forecasted data Rp, thetap, and Sp, which are stored in a buffer 6, by correlators 2, 3, and 4 concerning the range, the azimuth, and the signal intensity, respectively; and if the input difference is within an allowable range, data R1, theta1, and S1 stored in the buffer 1 are transferred to a format register 5. The forecasting operation based on correlated target data R1, theta1, and S1 is performed in a forecasting operator 8, and operation results Rp, thetap, and Sp are transferred to a tracking information memory 7 to update forecasted data. | ||||||

PURPOSE:To eliminate the need for man to judge side lobe tracking or not by utilizing a nature of a monopulse antenna pattern to prohibit automatically antenna sidelobe tracking. CONSTITUTION:A signal received by a monopulse antenna 1 is inputted to amplitude detectors 4a-4c and phase detectors 5a, 5b through mixers 2a-2c and amplifiers 3a-3c. Outputs from the phase detectors 5a, 5b are inputted to a tracking signal processor 7. Outputs from the amplitude detectors 4a-4c are inputted to an amplitude comparator 9 through weighting circuits 8a, 8b. The amplitude comparator 9, when a sum channel signal is smaller than a difference channel signal, actuates a tracking prohibition controlling circuit 10 to cause a tracking prohibition. | ||||||

The system and method for standoff detection of human carried explosives (HCE) automatically detects HCE (112) up to a range of (200) meters and within seconds alerts an operator to HCE (112) threats. The system (100) has radar only, or both radar and video sensors, a multi-sensor processor (102), an operator console (120), handheld displays (122), and a wideband wireless communications link. The processor (102) receives radar and video feeds and automatically tracks and detects all humans (110) in the field of view. Track data continuously cues the narrow beam radar (118) to a subject of interest (110), (112) the radar (106), (108) repeatedly interrogating cued objects (110), (112), producing a multi-polarity radar range profile for each interrogation event. Range profiles and associated features are automatically fused over time until sufficient evidence is accrued to support a threat/non-threat declaration hypothesis. Once a determination is made, the system (100) alerts operators through a handheld display (122) and mitigates the threat if desired. | ||||||
