Example Embodiment
[0028] Example 1: see figure 1 The present invention is an acousto-optic automatic target reporting system, including: a detection light curtain L, an amplifier circuit, a data acquisition device, a coordinate calculation unit and a display part, the present invention also includes a microphone array, and the detection light curtain L and the microphone array simultaneously The flying projectile is measured, and the captured signal is transmitted to the data acquisition device through their respective amplifiers, giving the target information of the flying projectile measured; when the supersonic flying projectile passes through the detection light curtain, the detection light curtain outputs a trigger pulse to make The data acquisition device starts to work, and then the shock wave signal generated by the supersonic flying projectile is detected by the microphone array and the corresponding signal is output. After the signal is amplified by the amplifier circuit, it is collect...
Example Embodiment
[0031] Embodiment 2: The main body composition is the same as that of Embodiment 1, see figure 1 .
[0032] The microphone array of the acousto-optic automatic target reporting system is two, and each microphone array is composed of three microphones. , the two microphone arrays and the detection light curtain L are in the same plane.
[0033] The present invention has no special requirements for the position of the microphone in the sound array, which greatly reduces the installation requirements of the microphone and the machining accuracy of the microphone fixing device, thereby reducing the manufacturing cost of the entire system.
Example Embodiment
[0034] Embodiment 3: the main body is formed with embodiment 2, and the arrangement of the two microphone arrays of the automatic target reporting system is: the connection line of the three microphones is a triangle, and the arrangement rule of the microphones is that the three microphones are arranged around the center point of the array, and the three The wires of the microphones form a triangular combined array. see figure 2. In this example, the triangle of the microphone array is an equilateral triangle. In the first microphone array, the microphone S1, the microphone S2, and the microphone S3 are located around the center point 01 of the array, and they are all equidistant from the center point 01 of the array. The lines form an equilateral triangle combination.
