摘　　要：根据ＧＬＯＮＡＳＳ系统的频率计划和ＧＬＯＮＡＳＳ接收机的特定结构，提出用变化钟频法实现ＧＬＯＮＡＳＳ接收机的前端．对相应的前端频率合成器部分提出了具体要求，并给出了基于集成频率锁相环的频率合成器的设计与实现．讨论了固有合成频率偏差的来源和消除办法．分析了频率合成器的性能指标．实验表明，该合成器稳定性好，精度高。A GLONASS receiver front end structure and its frequency synthesizer part are given based on the GLONASS frequency plan. The synthesizer is realized with integrated PLL frequency synthesizer. It is easy to be constructed and also has the advantage of good stability. The design details of the frequency synthesizer is given. The inherent synthesizing error is analyzed and the method of eliminating it is discussed. The theoretical performance of the synthesizer is provided. The experiments show that the synthesizer has good stability and high precision. It meets the requirements and can be applied to the GLONASS receiver.
