| Abstract: | Before launching into the orbit,the space-borne SAR must receive strict tests to ensure that its performance meets requirement.Aiming at the problems that these tests have heavy workloads and need various kinds of instruments,and data record is incomprehensive,a design of general experiment recorder is introduced.With FPGA as its core,this recorder accomplishes the functions of acquisition and generation of analog signals,transferring auxiliary data,recording small amount of data,acquisition of remote testi... |
