Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guided missile that detects infrared rays or reflected signals from a target, and captures and tracks the target. First, the conventional B5 bullet y will be briefly explained. In Figure 1, (1) is the target that the guided missile captures and approaches;
(4) is the receiver (i device) that extracts the error signal from the signal received by antenna (3); (5) is the receiver.

Antenna servo device (6) is an antenna servo device that directs the antenna (3) in the direction of arrival of the signal g (2) from the target using the error signal of the output of the device (4); A steering device that steers the aircraft toward the meeting point with the target using an error of 4M, and a rocket motor that provides thrust to the guided missile until +71r. The purpose is to guide the aircraft to the meeting point with the target and ultimately reach the target.

However, the conventional @ grenade has a velocity characteristic (V) as shown in Figure 2, so the longer it takes to meet the target, the lower the velocity. Therefore, it becomes impossible to follow the rapid movement of the target (such as when the speed increases rapidly), resulting in a decrease in the ability to shoot down the target. Especially in recent years, there has been a strong tendency to make guided missiles more expensive, and the above-mentioned drawbacks have been highlighted. This invention is characterized by improving the above-mentioned drawbacks, and has a newly provided configuration that describes the output of the receiving device (4). By achieving a predetermined tracking characteristic at the stopping and meeting points, the aC power for shooting down the target is improved.

The guided missile of the present invention will be explained below using FIG. 3, which is a specific example.

In FIG. 2, (1) to (7) are the same as in FIG. 441. +81. +91 is a new 71Fl for @1 figure
Then, the fC device calculates the meeting time to the target from the output of f8) Fi and the receiving device (4), and calculates the meeting time (before the set meeting time).
To) is an operation start time setting circuit that generates a starting ignition signal for the auxiliary rocket motor (9), and (9) is an operation start time setting circuit that generates a start ignition signal for the auxiliary rocket motor (9). , ″@Support rocket motor.

Since this invention is constructed as described above, the velocity characteristics of the bullet are as shown in FIG. Therefore, if the distance to the target is within a predetermined range using the above-mentioned additional function, the speed will be corrected and the target will be ii! If you accelerate rapidly to escape from the grenade, the ej4 bullet will also be fired at 1 speed. Thereby, the visibility of the guided missile can be improved. In addition, in the dice example, +81
゜ (9) are shown as independent ones, but this one is +81. Needless to say, it may be replaced with a single component having +91 functions.
