Problems solved by technology

This automatic target reporting device is only suitable for short-distance (generally less than or equal to 200 meters) direct shooting. Their sensors are included in the sealed target cavity so that the coordinate calculation and signal processing exclude the wind speed, wind direction and other environmental factors in the wind field. The interference factors of other shock waves and clutter are only suitable for shooting training of direct light weapons, not suitable for shooting training of heavy weapons, such as tanks, cannons, and rockets.

Embodiment 1

[0032] Embodiment 1: as Figure 2-6 As shown, an open three-dimensional array ultrasonic automatic target reporting device includes a target frame 1, a computer, a display, and a power supply. An ultrasonic sensor 2, an ambient temperature compensation sensor 3, and an ambient wind speed and direction compensation sensor are installed on the target frame 1. Instrument 4, data acquisition and processor 5;

[0033] The number of the ultrasonic sensors 2 is six, each of the six ultrasonic sensors 2 is in a row of three, and they are all on the same horizontal line in the horizontal and vertical directions, and the six ultrasonic sensors 2 are all on the same horizontal plane and are at a certain distance from the horizontal plane. Angle;

[0034] The ambient wind speed and direction compensator 4 is fixedly installed on the target frame;

[0035] The ultrasonic sensor 2, the ambient temperature compensation sensor 3, the ambient wind speed and direction compensation instrument ...

Embodiment 2

[0053] In order to better understand the present invention, the measurement principle of the open three-dimensional array ultrasonic automatic target reporting device of the present invention is as follows:

[0054] Such as figure 1 As shown, before establishing the mathematical model, some important assumptions are put forward without affecting the actual situation. Assume that the trajectory of the projectile is a straight line, ignoring the height of the trajectory; assume that the trajectory of the projectile is not affected by the wind; assume that the projectile is vertically incident on the target surface, and the velocity of the projectile is v>c (speed of sound). When a projectile flies in the atmosphere at supersonic speed, the air is disturbed by the projectile to produce a pressure wave of density change, which is usually called projectile shock wave. The trajectory of the projectile shock wave at each point on the trajectory forms a cone with the apex at the hea...

Abstract

The invention provides an open three-dimensional arrangement type ultrasonic automatic target-reporting device. The open three-dimensional arrangement type ultrasonic automatic target-reporting device comprises a target holder, a computer, a display and a power source. Six ultrasonic sensors, an ambient temperature compensation sensor, an ambient wind speed and direction compensation apparatus and a data acquisition processor are mounted on the target holder, every three of the six ultrasonic sensors are in a horizontal row, the six ultrasonic sensors are positioned on the same horizontal line in both horizontal and vertical directions and are positioned on the same horizontal plane, and a certain included angle is formed between the horizontal plane and each of the six ultrasonic sensors. The open three-dimensional arrangement type ultrasonic automatic target-reporting device has the advantages that the target holder with the six ultrasonic sensors is used, an acoustic model of an exterior ballistic trajectory is established by an ambient compensation circuit according to a geometrical relationship between supersonic speed shell shock wave shapes and an ultrasonic sensor array by means of applying ultrasonic inspection, an acoustical principle and an aerodynamics modeling method, and intersection points of pill tracks of direct aiming light weapons and heavy weapons and target surfaces are solved finally according to parameters of measured sensor time and the like so as to solve coordinates of impact points. The open three-dimensional arrangement type ultrasonic automatic target-reporting device solves the problem of heavy weapon training.

Description

technical field [0001] The invention relates to an automatic target reporting device for directly aiming at light and heavy weapons in an outdoor shooting range, in particular to an open three-dimensional array ultrasonic automatic target reporting device. Background technique [0002] Ultrasonic automatic target reporting devices originated in the 1990s. Their working method is automatic target reporting for direct-pointing light weapons shooting training. Its characteristic is that the automatic target reporting device includes a target cavity, and the outer surface of the target cavity is pasted with aiming devices such as chest ring target paper. This automatic target reporting device is only suitable for short-distance (generally less than or equal to 200 meters) direct shooting. Their sensors are included in the sealed target cavity so that the coordinate calculation and signal processing exclude the wind speed, wind direction and other environmental factors in the win...
