Target detection device and method

Abstract

The invention relates to the technical field of fuzes, and provides a device and method for detecting a target exit time point. The detection device at the time of target exit includes an acceleration acquisition unit, a DC blocking amplification unit, and a signal processing unit. The acceleration acquisition unit collects the acceleration signal of the penetrating fuze during the penetration process and transmits it to the DC blocking amplification unit; Perform DC blocking and amplification processing to obtain an amplified signal and transmit it to the signal processing unit, wherein the amplified signal includes a first signal greater than the set threshold and a second signal less than the set threshold; the signal processing unit reverses the second signal After phase phase, it is added to the first signal to obtain a mixed signal, and the peak value detection is performed on the mixed signal to obtain a peak signal, and the time point corresponding to the second peak signal is used as the target time point. Compared with the prior art, the present invention improves the problem in the prior art that the target time point cannot be accurately detected, which leads to misoperation of the penetration fuze.

Description

Technical field [0001] Embodiments of the present invention relate to the field of trusting techniques, in particular, to a target timing detecting apparatus and method. Background technique [0002] The trust is a device for controlling an ammunition by a predetermined condition by a perceive object and environment. In modern war, in order to maximize the enemy's deep embedded an important military equipment in the holes of steel armor, concrete (target), as required, the body must be exploded after the target, which involves the provision Population technology. [0003] At present, the invasion of the tribute explosion system uses acceleration to invade the letter. The acceleration invasive lettering device is to identify the accelerometer acquired by setting the accelerometer to determine the momentum of the elastic penetration target to completely destroy an important military equipment deeply underground. [0004] The acceleration signal acquisition of the accelerometer in t...
