Design And Implementation Of Laser Radar Signal Processor

Pulse Laser Range radar has a lot of advantages, including high precision, range accuracy has nothing with the distance in measurement, small systems and rapid in measurement, have been widely used and researched. However, because of the narrow laser pulse and low-echo peak, the two targets in ranging precision and the distance in measurement have always been difficult to achieve. Traditional methods use ranging pulse counter to achieve high-precision in measurements, but it is difficult to design and cannot detect multi-target. Therefore, this paper has broken the traditional design methods, using the method of high-speed AD with the highest sampling rate in2.4GHZ combined with FPGA in high-speed interface and rapid computing capability of floating-point DSP to design a signal processing system of Pulse Laser Range Radar, and greatly increased the precision in range and the distance in measurement.The main difficulties of this paper are how to realize the sampling of high-speed data, transmission and processing. First, the basic principles of radar ranging and basic ranging method are introduced; Secondly, the hardware design is introduced, and focuses on the analysis of the software design and debugging of FPGA and DSP. At last, the verification of main parameters and the test results in this system are given, and the key issues involved in the technology and implementation are summarized, and gives the system of improvements and optimization methods.
