- 摘要:
- 在整部雷达项目的研制和生产中,由于雷达外场调试难度大,若全部采用外场试飞,成本太高且外界影响因素太大反而在很多情况下不便于调试,因此雷达目标模拟技术开始盛行。在雷达目标回波模拟中,雷达回波模拟数据的产生有很多种方法,普遍是外接一个雷达目标模拟器产生波形。通过介绍Cordic算法原理,借用Cordic算法设计了一种更简单、便捷、易操作的雷达自发产生目标模拟数据的方法,在FPGA中通过相位变化叠加目标信息。此方法便于项目内部使用,不需借用其他硬件,即可在雷达内部FPGA模块自发产生模拟目标回波数据发送至信号处理板,达到快速验证数据通路、信号处理、数据处理的基本功能的目的,且通过仿真和上板验证了该方法有效,具有一定的实用性。
- Abstract:
- In the development and production of the entire radar project, due to the difficulty of radar field debugging, if all field test flights are used, the cost is too high and the external factors are too large, but in many cases, it is not easy to debug, so radar target simulation technology has become popular. In radar target echo simulation, there are many ways to generate radar echo simulation data, and it is common to connect an external radar target simulator to generate waveforms. This article introduces the principle of the Cordic algorithm and borrows the Cordic algorithm to design a simpler, more convenient, and easy-to-operate method for radar to spontaneously generate target simulation data. In the FPGA, the target information is superimposed by phase change. This method is convenient for internal use in the project. Without borrowing other hardware, the simulated target echo data can be spontaneously generated in the radar internal FPGA module and sent to the signal processing board to quickly verify the data path and signal The purpose of the basic functions of processing and data processing, and the effectiveness of this method is verified through simulation and boarding, and it has certain practicability.
