摘要
多通道雷达回波接口单元作为MIMO雷达实验系统中的一部分,它可以基于上位机中的目标特性数据库仿真计算出雷达回波信号,并将多路回波信号通过高速接口传送到信号处理板进行计算判决。所设计的接口单元采用DSP+FPGA架构,通过串口从上位机获取数据,通过LVDS进行板间回波数据的传输,实验表明,接口单元可较好完成四通道雷达回波数据的实时传输。
As a part of the MIMO radar experimental system, the multichannel radar echo interface unit can simulate the radar echo signal based on the target characteristic database of the host computer, and it transmits multichannel echo signal to the signal processing board by high- speed interface. The interface unit uses the architecture of DSP ＋ FPGA, it obtains the data from the host computer by the serial port and transmits the echo data between the board by LVDS. The experimental results show that the interface unit can complete real- time transmission of four channels radar echo data.
