| PURPOSE:To make a high-degree tracking control of a moving object possible by selecting and applying the most effective algorithm in accordance with internal and external conditions of a tracking control system. CONSTITUTION:With respect to algorithms of the moving object tracking control which are used experimentally, the algorithm considered to be most effective at each time is selected and applied in on-line and real time on a basis of observation data obtained momentarily; and availabilities of algorithms at each time are discriminated in accordance with features of algorithms and conditions of the system or the like to select the most available algorithm, and parameters of features, conditions, and availabilities are grasped by data of simulation. However, the quantity of data which can be analyzed quantitatively is small, and most of them are based on qualitative discrimination; and then, procedures of algorithm selection are executed by the ambiguous logic (FUZZY decision making). The algorithms used in estimating and control mechanism 2 and 3 are determined in accordance with selecting procedures by a decision making mechanism 5 to perform always the high-degree tracking control of the moving object without influences of the variance of conditions. | ||||||

| PURPOSE:To extend a detection distance and to improve distance tracking precision by outputting a transmitter output to a searching radar and a tracking radar over switching, and imposing pulse compressing processing upon a signal for the tracking radar. CONSTITUTION:The reference signal of a reference signal generator 11 is distributed into two by a distributor 10; one is pulse-modulated by a pulse modulator 5 and the other is modulated into FM pulses by an FM modulator 9. The outputs of the modulators 5 and 9 are switched alternately by a reference signal switch 7 on the basis of the control signal of a switching controller 8 and inputted to a transmitter 1 to generate a high frequency signal. The high frequency signal of the transmitter 1 is switched by a high frequency switch 6 synchronously with the switch 7 according to the control signal of the controller 8 to supply the output of the modulator 5 to the searching radar and the output of the modulator 9 to the tracking radar 4. Transmit pulses are radiated from the radars 3 and 4, reflected by a target, and received to perform receive signal processing. The radar 3 uses the pulses without varying the pulse width and the radar 4 performs pulse compression to obtain narrow pulses. | ||||||

| PURPOSE:To operate efficiently the transmitting power of a transmitter used for search and tracking, by performing the feedback control of the distribution ratio of the transmitting power in accordance with an excess tracking radar receiving power detection value. CONSTITUTION:A tracking radar receiving power is detected through a tracking antenna 4, a tracking receiver 5, etc.; and if the receiving power detection value is excess because a target is at a short distance or is large-scaled, the feedback control of a variable power distributor 12 is performed by a power distributor driving circuit 13. Thus, the distribution ratio to power for tracking and power for search of the transmission output of a transmitter 1 used for tracking and search is adjusted automatically, and the transmission output is operated efficiently without damaging the tracking precision. | ||||||

| 153 | Sweep system | JP5025981 | 1981-04-03 | JPS57165776A | 1982-10-12 | YAMANE HIDEO |
| PURPOSE:To shorten the locking time without deteriorating the lock sensitivity of a frequency following loop by imparting the function of changing over the sweep velocity to the frequency following loop. CONSTITUTION:When signal in the Doppler range is applied to the mixer 1, the sweep circuit 7 applies first sweep signal of high speed to a voltage control oscillator 10 through a summing amplifier 8 and so on. Next, the output signal of the mixer 1 changes its frequency in response to the sweep signal. When this frequency exceeds the set value of a lock judgement circuit 5, it is stored in the memory circuit 6, and next, the content in the memory circuit 6 is applied to the sweep circuit 7 during sweeping and the sweeping speed becomes slow by the portion of the frequency that is stored in the memory circuit 6. With imparting the function to change-over sweep speed to the frequency following loop, the locking time can be shortened without deterioration lock sensitivity. | ||||||

| PURPOSE:To enable searching and tracking of a target to be accomplished simultaneously with simple constitution by using a fan beam for the beam to be radiated from an antenna, and so constituting the system that this fan beam is rotated. CONSTITUTION:When the movable terminal 8a of a switch 8 is changed over to the stationary terminal 8b side, the transmitted electric power radiates a fan beam 1 from an antenna 2 to targets A, B, and the reflected echoes thereof input to an indicating device 3 and a tracking device 6 via a transmitter-receiver 4. In the tracking device 6, the received echoes and the rotation angle signal of the antenna 2 are compared and the error signals of angle of elevation and azimuth are transmitted to an antanna driving part 7, by which the bearing and the angle of elevation are changed while the antenna 2 is being rotated in the direction of an arrow a1. Next, in the case of operating this as a search radar system, the movable terminal 8a of the switch 8 is changed over to the stationary terminal 8c side. The antenna 2 rotates in the arrow a3 direction around the y-axis, and this system serves as a search radar. In this way, the searching and tracking are accomplished simultaneously with the simple constitution. | ||||||

| PURPOSE:To detect an abnormality in a tracking control system on the preliminary side independently of the present use side by applying a false RF differential signal modulated as prearranged to the preliminary system and monitoring the output of a speed dynamo on the preliminary side through the intermediary of an antenna drive motor on the preliminary side. CONSTITUTION:The tracking drive of an antenna 10 based on a prearranged pattern is controlled through the intermediary of a currently used motor 8 to be controlled through feedback by each device of the current use. In this case, a false RF differential signal modulated according to a pattern from a pattern modulator 22 is applied to an auxiliary motor 17 through an auxiliary trackig reception device 3, an auxliary control amplification device 5, an auxliary drive power amplification device 7, etc. which make up a preliminary system. Then a speed power generation output generated by an auxiliary machogenerator 18 following the turning of the motor 17, is compared with a pattern signal which is output by a pattern generator 21 to which a false RF differential signal is added. An abnormality identification circuit 24 detects an abnormality in the preliminary-side tracking control system independently of the currently used system at time of the operation of the currently used system. Thus it is possible to prevent the deterioration of an operating rate due to an abnormality in the preliminary system. | ||||||
