Abstract—the paper designs and implements a six-channel digital preprocessor system. The preprocessor system is designed as much digital structure as possible, by calling the corresponding software packages, the basic hardware parameters of preprocessor system can be adjust to meet different needs in specific applications. Compared with the conventional preprocessor circuits, the digital preprocessor system has virtues of high sensitivity, low power consumption, standardization and software-based, more over, it is capable of network building. The digital preprocessor system has been applied in a target detection system, the experiment results show that the method is very promising.
Index Terms—digital preprocessor system; software packages; digital AGC; Intelligent Communication Node
