| Abstract: | The digital receiver design of phase array radar has developed rapidly these years thanks to the use of high-performance chip and large-scale digital integrated circuit. Digital frequency conversion is an important technology in the design of the digital receiver design, where many problems exist related to its realization. When the number of the data channel is big, how to guarantee the synchronization between each other is a difficult problem. The paper firstly analyses several issues including the digital orthogonal mixing, multi-channel FIR filtering and the synchronization. The work has been designed and verified on FPGA. |
