Abstract:

Due to the limitations of system power consumption and space, the conventional ammunition laser fuze is unable to use a plurality of lasers and laser receivers for multi-transmitting and multi-receiving,and therefore the traditional large field-of-view (FOV) laser detection method can not meet the requirements of system miniaturization. A new large FOV single transceiver bidirectional-driving detection scheme is proposed,a mathematical model is established, and the target acquisition rates at the different projectile-target distances and the different projectile spin rates are analyzed. For the electromagnetic interference factors, a prototype is manufactured, and a variety of methods are used to shield the electro-magnetic signals. The anti-electromagnetic interference experiment and the detection experiment of targets at different distances are performed. The results show that the scheme can effectively shield the electro-magnetic interference; ensure that a target can be captured at the distance of 8 m when the spin rate of project tile is 50 000 r/ min; and make the application of laser fuze with large FOV detection capability in conventional ammunition possible.

Key words: ordnance science and technology, laser fuze, single transceiver, large field-of-view detection, target acquisition
