Abstract

A measurement device and a measurement method for a roll angle of a bullet body belong to the field of signal measurement. The measurement device comprises the bullet body. The measurement device and the measurement method are characterized in that the measurement device comprises a signal processing module arranged in the bullet body and a plurality of infrared diode pairs which are uniformly arranged on the external surface of the bullet body; the infrared diode pairs are arranged in one longitudinal section of the bullet body and form an infrared diode pair ring; each infrared diode pair comprises an infrared transmitting diode and an infrared receiving diode; and each infrared diode pair is electrically connected with the signal processing module. Through uniformly arranged the infrared diode pairs on the surface of the bullet body, a modulated wave is transmitted through the infrared transmitting diode wherein, and then the modulated wave is reflected and is received by the infrared receiving diode of the same infrared diode pair, thereby generating a pulse sequence signal, and calculating the roll angle of the bullet body by the signal processing module. The measurement device for the roll angle of the bullet body has advantages of simple structure, high response speed, wide measurement range, high convenience in mounting and debugging, easy calculation, easy operation and high suitability for popularization.

Description

technical field [0001] The invention belongs to the field of signal measurement, and in particular relates to a measuring device and a measuring method for the roll angle of a projectile body. Background technique [0002] With the development of modern electronic technology, various high-precision guided weapons have been developed rapidly. Guidance methods such as radio, infrared, laser, GPS, inertial navigation, and television have emerged in an endless stream, greatly improving the accuracy of weapon attacks. Especially in the inertial component guidance method, a large number of methods such as gyroscopes, accumulators, and magnetometers are used to accurately measure and calculate data such as projectile rotation speed, flight speed, pitch, roll, and yaw, which have been widely used. is of great significance. However, in the planning stage of many guided weapons, the rotational speed of the projectile is usually affected by multiple factors and is an uncertain value. ...
