| 201 | Radar tracking system | JP3961583 | 1983-03-09 | JPS59163582A | 1984-09-14 | MITSUBORI TAKASHI |
| PURPOSE:To retrack exactly only a video by a former target by continuing an observatin by an extrapolation forecasting when a tracking target disappears temporarily, also retracking it by using a radar sub-tracking part, deriving the movement data, comparing them with the former movement data to discriminate whether the target is the former target or not. CONSTITUTION:When a target video which has disappeared in the next time appears again in a tracking gate, it is decided that a target exists by a level deciding device 5 of a radar main tracking part 16 and a sub-tracking part 17, and a signal i2 is sent to a deciding part 21. Subsequently, when retracking of the target is started, a calculating part 18 calculates movement data (x) such as a position, speed, acceleration, etc. of the target, basing on a tracking data (w) outputted to a signal processing part 15 from the radar sub-tracking part 17, and these data (x) are compared with the movement data (y) immediately before the video disappears, and only when they are within some allowable range, the target is decided to be the same as the former target. As a result, a retracking permitting pulse (q) is outputted to the main tracking part 16 and a deciding part 21 from a comparator 19. While the pulse (q) is effective, the main tracking part 16 sets the contents of a distance counter 9 to the tracking data (w) of the sub- tracking part 17, makes the tracking gate position of the main tracking part conform to that of the sub-tracking part to secure to catch the target. | ||||||

| PURPOSE:To obtain accurate, stable performance, by providing a loop gain controller to a distance tracking part and correcting variation in error detection sensitivity due to a difference in the condition of a target. CONSTITUTION:The loop gain controller 7 is arranged at the distance tracking part to discriminate the condition of the target from a distance signal, antenna elevation angle, and machine-body pitch signal, correcting the variation in error detection sensitivity. For example, when an angle of incidence decreases, an error detector 6 decreases in error detection sensitivity. The loop gain control circuit 7 discriminates the condition of the decrease in error detection sensitivity from the distance signal, antenna elevation signal, and machine-body pitch signal and a control error signal E is outputted after the error signal is amplified properly. | ||||||
| 203 | Method and device for displaying distance/azimuth ship image in order to control weapon | JP11002983 | 1983-06-17 | JPS5927279A | 1984-02-13 | SORU BOORUZU |
| Distortions inherent in the formation of a range/doppler image by an airborne Synthetic Aperture Radar (SAR) of a ship under the influence of roll, pitch, and yaw motions characteristic of a sea state conditions, are removed by the formation of a scaled range/azimuth image generated with the use of an interferometer antenna in conjunction wth the SAR. A least squares linear regression solution to doppler processed interferometric azimuth angle data derived from ship radar reflections permits the determination of aircraft to ship relative rotational motion essential to the development of such an improved high resolution radar image, so that continuous automatic tracking of a cursor imbedded in a single designate resolution cell of the ship's displayed image essential to carrying out precision standoff command weapon guidance to that selected ship target cell, can be accomplished. | ||||||
| 204 | Guided air frame system | JP8757282 | 1982-05-24 | JPS58204382A | 1983-11-29 | OKUGAWA HARUKI |
| PURPOSE:To increase equivalently the gain a phased array antenna, by correcting a launching forecasting angle by a target speed in case when a launching forecasting angle calculated in accordance with target information which is caught is larger than an angle decided in advance. CONSTITUTION:A radar 2 radiates radio waves 3 to a target, receives a reflecting signal 4, and extracts targer information. A future position of the target, a forecasting hit point and a launching forecasting angle are calculated by a control computer 5 from said target information. In case when a forecasting angle is large than a value set in advance, a forecasting angle correcting circuit 12 subtracts the forecasting angle by some angle being proportional to a target speed, and gives a command to a launching machine 6 as to the correcting forecasting angle. | ||||||

| PURPOSE:To catch a target quickly by controlling a main beam electronically according to the target presence probability around target indicating position, and catching the target. CONSTITUTION:In a scanning pattern generating part 1, scanning pattern signals C, D for searching a searching range regulated by a certain target presence probbability are generated. In an addition part 2, the outputs C, D from a target indicating position P and the part 1 are added and the positions are determined successively in higher order of the presence probability of the target. In a phase controlling part 9, respective phase devices 10 are operated in accordance with these searched positions, whereby the direction of the main beam is controlled. As a result, the main beam of phased array antennas 8 search the circumference of the position P until the target is caught. | ||||||

| PURPOSE:To improve a data rate of target tracking, by using plural radiation faces or reflection faces of an antenna to form plural tracking beams with one face. CONSTITUTION:A target searching and tracking beam 25 searches a target in the coverage by rotating the radiation face in the direction of the azimuth mechanically. Beams 26 and 27 only for tracking are radiated with radio waves and receive echo signals only when these beams are directed to the direction of the target detected by the beam 25. Consequently, a high data rate of three-fold antenna rotation time is obtained. | ||||||

| PURPOSE:To perform sepn. and identification of the case in which the positions of plural aircrafts are in proximity to each other by correlating the positions of a target detected with a radar and speed information. CONSTITUTION:The target position information by the past distance RT and bearing thetaT detected with a radar and the speed information by the frequency deviation are correlated with the forecast distance, bearing and speed information RP, thetaP, VP through a memory 7 and a buffer memory 6 via a tracking target data forecasting part 8 in accordance with these sets of information with correlators 2-4. When the differences between these sets of the information are less and the correlations are obtained, the current input target information is fed via a controller 5 to the part 8. When no correlations are obtained, the buffer 6 is controlled by the controller 5 and the another forecast information is transferred to the correlators 2-4 in order to obtain the correlations, whereby the sepn. and identification of the case in which the positions of plural aircrafts are in proximity to each other are accomplished surely. | ||||||
