Laser pulse code is an anti-jamming measures used in semi-active laser guided weapons. On account of the laser-guided signals adopting pulse coding mode and the weak signal processing  it need complex calculations in the frequency measurement process according to the laser pulse code signal time correlation to meet the request in optoelectronic countermeasures in semi-active laser guided weapons. To ensure accurately completing frequency measurement in a short time  it needed to carry out self-related process with the pulse arrival time series composed of pulse arrival time  calculate the signal repetition period  and then identify the letter type to achieve signal decoding from determining the time value  number and rank number in a signal cycle by Using CPLD and DSP for signal processing chip  designing a laser-guided signal frequency measurement in the pulse frequency measurement device  improving the signal processing capability through the appropriate software algorithms. In this article  we introduced the principle of frequency measurement of the device  described the hardware components of the device  the system works and software  analyzed the impact of some system factors on the accuracy of the measurement. The experimental results indicated that this system improve the accuracy of the measurement under the premise of volume  real-time  anti-interference  low power of the laser pulse frequency measuring device. The practicality of the design  reliability has been demonstrated from the experimental point of view.

The strong electromagnetic interference (EMI) generated in high-power TEA C02 laser system mainly comes from main discharge circuit  pulse spark switch and power supply. Such strong EMI causes great damage and interference to the control system based on DSP. In this paper  we present the interference sources and their distribution and propose the methods of anti-interference. Measures for hardware design include weakening transient ground potential difference by using equipotential lines between devices  using signal isolation interface to inhibit the transient ground potential interference  and rational layout  shielding and filtering to the control system. And methods for software design include range-limited filter  self-diagnosis and self-repair for the critical data and anti-interference during abnormal reset. The EMI has been inhibited effectively by the anti-interference method proposed above. The result shows that: the software anti-interference method is as important as the hardware anti-interference method for the control system in a complex environment of strong EMI. 2010 IEEE.
