Abstract

PURPOSE:To permit impact against a target with a simple constitution and a good accuracy, by a method wherein the amount of speed control is operated from a range information and the changing amount of angle of line of sight while the speed of a missile is determined based on the operated speed. CONSTITUTION:A guiding device in a missile M detects the angle of deviation of a target with respect to the advancing direction of a missile and the angle theta(t) of line of sight while an angle of line of sight changing amount operating unit 12 operates the changing amount DELTAtheta of the angle theta (t). Acceleration (g)(t), applied on the missile M, is detected to obtain the position of the missile M time by time and the position of the target is detected by a target position detecting unit 16 whereby an information on a range to the target is obtained. A speed control amount dl/-dt for intercepting the target by the missile at a predetermined position is operated from the given information. The speed control amount dl/dt is increased or decreased in accordance with the changing amount (theta'-theta) of the angle of line of sight, for example, to control the thrust of the missile. According to this method, the missile may intercept the target T at a point C.

In the above configuration, the speed control means will be explained below with reference to FIGS. 2 to 4.

On the other hand, the flight path and speed of the ballistic bullet T are predictable,
It is easily detectable by radar. It is assumed that an Imaichi ballistic missile T flies along a path as shown by the dotted line in the middle of Figure 3.When this ballistic missile T reaches point A on the path, a missile M is launched from point D, and at point C on the path, the ballistic missile T flies. In order to make missile M meet at , if the speed of ballistic bullet T is Ts and the speed of missile 1 is Ms, then AC/Ts = CD/Ms, so Ms = (AC/CD)Ts, the missile M's speed is speed can be determined.

In this case, although the ballistic bullet T does not move by itself, its path may change by several looms due to disturbances such as changes in the density of the atmosphere. By changing the path angle of the missiles using proportional navigation, it is possible to bring the missiles together at a position that is slightly different from the zero point, but as described above, this would complicate the guidance system. Therefore, in this invention, the speed of the missile M is controlled so that it meets the target at the zero point.

On the other hand, the accelerometer 13 detects the acceleration g (t) applied to the missile M, and the missile position detecting section 14 double-integrates this acceleration g (t) to determine the momentary position of the missile M. At the ground station, the receiving section 15 receives the radar information, the target position detecting section 16 detects the position of the target T, and transmits it to the missile M. Also,
If the seeker 11 is a radar seeker, distance information from the seeker 11 to the target can be obtained.

The distance ML between the missile M and the target T derived from their respective positions (this distance can be directly obtained with a radar seeker), the speed control amount dJ/dt of the missile M, and the visual line angle change amount Δθ are vectors. When displayed, it becomes as shown in FIG. 4, and can be expressed as dJl/dt L · Δθ. Therefore, the speed calculation unit 17 calculates the speed control amount dj/dt of the missile M from the distance At L between the missile M and the target T and the visual angle change amount Δθ, and sends this speed control information to the thrust control device 18.

For example, if the eye angle change (θ'-〇) is positive, dj/
The thrust of the missile is controlled so that it is decelerated by dt, and if it is negative, it is accelerated by dJ/dt. As a result, the missile M and the target T can meet at the zero point, and the defense range can be made wider than the interception range. The thrust can be controlled by, for example, increasing or decreasing the opening of the rocket head (spark plug).
