摘要
脉冲激光驱动电路的震荡会引起回波模拟的多目标、虚景和半导体激光器损坏等问题。针对这类问题,从RLC放电回路理论出发,推导电流方程,运用极值原理,提出量化抑制震荡的方法。根据实际某火控性能要求,运用所推公式确立了关键参数。最后利用MPSL01型雪崩三极管作为高速开关器件设计电路,获得了峰值电流1 A,脉宽23.2 ns的窄脉冲电流,且反向电流几乎为零。采用C86119E型1 064 nm半导体脉冲激光器作为光源,构成回波模拟器发射系统。利用该单兵火控进行实际检测的结果表明,驱动器性能稳定,满足设计要求。
The oscillation from pulse imaginary scene of echo simulation, QI Haiying2 Changchun 130022, China; Changchun 130699, China） laser driving circuit can cause many problems such as multiple targets and damage to semiconductor lasers and so on. To deal with the problems above and starting from the theory of RLC discharge circuit, current equation was derived. Utilizing the principle of maximum, a method of suppressing oscillation quantitatively was proposed. According to the performance requirements of a fire control system, the key parameters were established by the formula derived above. Finally MPSL01 type avalanche transistor was used as a high speed switching device in the process of designing circuit. Then peak current of 1A and narrow pulse current of 23.2 ns were obtained. Furthermore the reverse current was almost zero. Semiconductor pulsed laser which type is C86119E of 1 064 nm was regarded as light source. And echo simulator launch system was composed. Actual detection was done by fire control system for single soldier. The results show that driving performance was stable and it can meet the requirements of design.
