Single-shot multi-receive area-scanning laser detection device assembled on non-rotating projectiles

Abstract

The invention discloses a single-shot multi-receiving area scanning type laser detecting device assembled on a non-rotating projectile. An annular opening is arranged in the casing of a bullet. The annular opening is covered by an annular transparent lens, and the annular transparent lens is fixed on the casing. A partition plate is fixed in the bullet and is located above a fuse. A driving motoris fixed on the partition plate through a motor bracket. A transmitting scanning reflection plane mirror is fixed on the output shaft of the driving motor. The transmitting scanning reflection plane mirror is equal to the annular transparent lens in height. A laser emitter is fixed on a laser emitting circuit, and the laser emitter and the laser emitting circuit are electrically connected. M receiving lenses are distributed circumferentially along the outer wall of the projectile body with uniform spacing. A photodetector is fixed on a laser receiving circuit. An inductive magnetic sheet is embedded in a motor shaft. A magnetoelectricity sensor is embedded in the inner wall of the casing and faces the inductive magnetic sheet to detect the target azimuth information. A main control circuitis fixed on the top face of the partition plate of the projectile. The device provided by the invention is for the problems of unavailable multi-shot multi-receiving small-caliber projectile and complicated structure of a single-shot single-receiving structure scheme.

Description

technical field [0001] The invention belongs to the field of laser detection, and in particular relates to a laser detection device in a single-shot and multiple-receive area-scanning mode assembled on a non-rotating bomb. Background technique [0002] The laser proximity fuze is an active photoelectric fuze. It irradiates the target with a laser beam of specific amplitude, time domain and space domain characteristics through the transmitting optical system, and the photoelectric receiving system receives the reflected echo of the target and performs real-time processing to complete the identification and detection of the target. Laser proximity fuzes play an important role in improving the hit rate and damage effect of modern precision guided weapons, especially surface-to-air missiles, air-to-air missiles and anti-radiation missiles. [0003] With the development of science and technology and the increasing diversification and complexity of the war situation (for example,...
