在微波综合孔径辐射计的数字相关处理系统中，多通道高速模数转换是关键环节。传统量化技术都采用具有同步逻辑的模数转换器，其性能优越，但消耗的系统资源相对较大，无法适应实际星载、机载等特殊环境要求。提出的异步量化技术能极大地简化系统设计，带来资源的节约，使得大规模的微波综合孔径辐射计系统可向实用方向发展。重点比较同步量化和异步量化技术在微波综合孔径辐射计中的差异，从理论上阐述异步量化技术引入的可行性，并通过 Matlab 建模仿真给出仿真结果验证理论分析的正确性。

Quantization technology for multiple channels is crucial in the microwave synthetic aperture radi-ometer.Traditional quantization technology applies analog digital convertors (ADC)with synchronous logics, which owns excellent performance while costs too much resource,and cannot adapt to special applications like satellites or aircraft.Asynchronous quantization can simplify the system and reduce the resource cost by large degree,which makes the microwave aperture radiometer more feasible in practice.This paper focuses on the difference of synchronous quantization and asynchronous quantization,studies the feasibility of introducing asyn-chronous quantization to the digital correlation system in theory,and then uses the matlab to build a model and make simulation to verify the theory validity.
