Abstract

PURPOSE:To improve target shooting down capacity by a method wherein the attitude angle of a control device and a flying route are controlled slowly in initial and intermediate periods but quickly in final period to prevent lock-off while the width of antenna beam is controlled in accordance with a relative distance with respect to a target to permit re-locking in a short period of time even when the lock-off is caused. CONSTITUTION:A relative distance detecting circuit 21 detects a relative distance between a target 1 and a control device M by the outputted target signal of a receiver unit 8 while a beam width setting circuit 22, outputting a relative distance signal, outputs a beam width control signal, setting a beam width in accordance with the relative distance upon inputting the lock-off signal by the outputted lock-off signal of a lock-off detecting circuit 20 and the outputted relative distance signal of the relative distance detecting circuit 21. A beam width control unit 23 controls an antenna beam width by the outputted beam width control signal of the beam width setting circuit 22. According to this method, even when the lockoff is caused in the beam width thetaB of the control unit, respective shifting amounts of a phase shifter group 6 are controlled in accordance with the relative distance with respect to the target whereby the beam widths of an antenna group 7 are controlled and re-locking may be effected in a short period of time.

Finally, the control device M either directly hits the target (1) or generates a detonation signal when passing near the target (1) to detonate the α field of the warhead and destroy the target (1). ) and shoot down target (1).

Just in case, target (1) turns with a large acceleration.

Or a target flying at high speed (against 11).

When the control device M attempts to fly in anticipation of that speed, the beam pointing direction and the axis direction of the control device M deviate greatly. Now, the angle between the axis direction of the control device M and the beam direction direction is called a beam scanning angle. The beam scanning angle needs to be controlled over a wider range as the target (1) turns with greater acceleration or as the target (1) becomes faster. If the beam scanning angle is narrow wt, the target (11) will appear outside the beam scanning angle range, and the controller MFi will lose sight of the target and lock off.

Particularly in recent years, overcoming the above has become an important issue due to the goal (1) of increasing speed and improving turning ability.

This invention adjusts the attitude angle and flight path of the control device M so that the target is within the beam scanning angle of the antenna group (71) and within the transmission/reception range of the dome (70). Yutsu: Control the end of the world as soon as possible.

In the control device M configured as described above.

The signals shown in FIGS. 2 and 3 are output from each device, and as shown in FIG. 4(a), in the conventional control device.

Even if the target motion can be maintained within the beam width θB at a long distance, if the target moves outside the beam width θB at a short distance, the beam width θB of the control device is changed as shown in Fig. 5(d). Even if the beam is locked off, by controlling the amount of phase shift of the phase shifter group (6) according to the relative distance to the target, the beam width of the Annan group (71) can be controlled and relocked in a short time. Become.

In addition, as shown in Fig. 4 (-), with the conventional control device, even if the target moves out of the beam scanning angle range at the end of the stage, the control device will not be able to control the target as shown in Fig. 4 (b) and (Q).
