射频与激光组合识别方案

分析了Mark XIIA敌我识别系统和激光敌我识别系统的现状，提出了射频与激光组合识别方案。该方案综合利用激光指向性高和Mark XIIA系统识别能力强的优点，通过并行使用射频询问射频应答工作方式和激光询问射频应答工作方式，避免了来自射频询问主波束内的多目标应答问题，在具备多目标处理能力的同时，提高了对密集目标中点目标的敌我属性识别能力。该方案也为单兵提供了可行的敌我识别手段。最后，论述了该方案的实用性，以期为新型敌我识别系统的设计提供参考。

A scheme for RF and laser combination IFF system

The Mark XIIA Identification of Friend or Foe (IFF) system and laser IFF system are analyzed, the design of Radio Frequency (RF) and laser combination IFF system is proposed. In the design, the high directivity of laser and the excellent identification capability of Mark XIIA system are used sufficiently. RF interrogation/transponder and laser interrogation/RF transponder operation modes are employed parallelly. Multiple responses within main beam of RF interrogation are avoided. With capability of multiple targets processing, rapid and reliable identification capability focused on point-target of battlefield can be improved. Meanwhile, feasible identification measure is also provided for individual soldier. Finally, practicability of proposed design is specified, which is helpful for the design of new IFF systems.
