英文摘要:
      The demand for accurate speed measurement increases with the rapid development of electronic science and technology in recent years. As the key component of speed measurement radar, the hardware circuits in real time speed measurement radars have essential impact on the accuracy and real time performance of the measurement results. Thus it is important to design high performance hardware circuits for speed measurement radars. This paper presents a hardware design for the speed measurement radars to improve the accuracy and real time performance of radar systems. The hardware platform is based on field programmable gate array (FPGA) thus the digital signal processing technique can be exploited to process the radar signals and control the radar system. The experimental results show that the proposed radar system maintains high performance for both low and high frequency signals。Thus the proposed system is applicable in real applications。
