| Abstract: | An eight-channel data acquisition system with data preprocessing function is designed for a multi-channel radar receiver. There are two kinds of high-speed output interface which are LINK port and CPCI bus. Sampling rate of its single channel is up to 125 MHz and the resolution is 14 bits. Hardware and software implementation is discussed in detail. Experiment results show that the effective number of bits is up to 9.9 bits and time delay difference is 40 ps. It has already been used in a certain radar rece... |
