With the wide application of multi-channel synchronous acquisition technology in various fields,it is possible to quickly accomplish the synchronous acquisition of multi-channel signals,which has become the key research topic of signal acquisition technology. At present,under the condition of strong interference,the traditional signal acquisition system that is a multi-channel signal acquisition is not synchronized,low sensitivity,bad antijamming. In order to improve the performance of communication signal acquisition,a strong interference synchronization acquisition system communication signal multi-channel environment was designed. First of all,the strong interference synchronous acquisition system hardware structure of multi-channel signal communication environment was designed,and the design process of the main hardware was introduced. Secondly,the communication signals of multi-channel synchronous acquisition system software was designed,the design and analysis of software development and programming were presented. The experimental results show that the system has high sensitivity in signal acquisition under strong interference environment,and has good synchronization ability for multi-channel signal acquisition,and has a strong anti-interference ability.
