Abstract
This paper presents the design and implement of multi-channel digital transceiver. The principles of the multi-channel IF digital waveform generation based on high-speed direct digital synthesis and the multi-channel IF digital receiver based on polyphase filtering are described in detail,both taking FPGA as the core. The proposed method can realize eight-channel full digital synchronization receiver with 250 MSPS sampling rate, eight-channel full digital synchronization waveform generation with 500 MSPS sampling rate, and high-speed real-time data transmission with data rate up to 2. 5 Gbps. The experimental results of the digital transceiver are given which satisfy the system requirement, the circuits are easy, flexible and versatile in digital array radar.关键词
