| Abstract: | The scheme for design a multi-channel IF digital receiver for DBF system radar is introduced in this paper. The analog I/Q demodulation is replaced by direct IF sampling and digital I/Q demodulation. The key technique of LVDS is used to solve the problem of high-speed multi-channel data transmission in the DBF system radar .The key design techniques of the receiver are analyzed in detail .The test results are also given in the paper. |
