Abstract: In view of the serious reality that the laser guided weapons are difficult to play their combat effectiveness due to the current active laser jamming, a dual wavelength intelligent cooperative laser guidance technology with strong anti-jamming ability is proposed. Based on the current situation and development trend of laser guided weapons at home and abroad, the overall concept of dual-wavelength multimode intelligent cooperative guidance with 1.06 µm pulse laser, 0.808 µm CW laser and Beidou Satellite Navigation System (BDS) is proposed. In the scheme, dual-wavelength multi-mode laser guidance is realized by multi-mode intelligent cooperative guidance attack technology, dual-wavelength multi-mode laser detection technology and multi-mode laser guidance anti-gamming technology. In the phase of 1.06 µm pulse laser guidance, random pulse code is adopted to prevent decipherment and laser deception jamming, and in the phase of 0.808 µm CW modulation laser guidance, narrowband filtering, correlation detection and other methods are used to resist sunlight interference. It is believed that the proposed scheme can improve the guidance performance, anti-jamming ability, and intelligent detection and identification ability of the existing laser guided weapons, and has impormant military value.
