中文摘要:
      比相法瞬时测频在电子对抗和空馈式雷达目标模拟领域占据重要地位。首先,介绍了比相法瞬时测频原理,设计了利用四路鉴相器实现瞬时测频的方法,并重点研究了四路鉴相器由低位向高位解模糊方法,给出了解模糊前后鉴相器二进制位构成和具体解模糊过程,该方法具有重要的工程参考价值。
英文摘要:
      The phase comparison method of instantaneous frequency measurement plays an important role in the field elec?tronic countermeasures and air-fed radar target simulation. Firstly, the principle of instantaneous frequency measurementby phase comparison method is introduced, and a method for realizing instantaneous frequency measurement by using a 4routes phase discriminator is designed. The method of solving ambiguity from low-bit to high-bit is emphatically studied.The binary bit composition of the before and after phase discriminators and the specific process of ambiguity resolution aregiven,which has important engineering reference value.
