四象限探测器测角系统需要同时满足系统反应时间短和误差小的要求。在分析了四象限探测器测角现有算法的基础上,提出了将插值法和传统算法相结合的一种改进算法,测角误差较小且容易实现。设计了适合实际应用的一套测角系统:模拟信号接收后,首先进行放大、去噪、相关检测等处理,随后进行模数转换,这一部分电路设计为目标方位检测电路;得到数字信号后,对其进行计算处理以得到偏移量,这部分系统以浮点DSP TMS320C6713为核心数字信号处理器,设计了6713的最小系统。另外,给出了以取13个特征点为例用反插值法设计的算法程序。
Four quadrant detector angle measurement system needs to meet the system response time is short and the error is small. Based on the analysis of the existing algorithms of four-quadrant detector angle measurement, an improved algorithm combining interpolation with traditional algorithm is proposed, which has a small angle error and is easy to implement. A set of goniometer system is designed which is suitable for practical application. After the analog signal is received, the first step is amplification, denoising, correlation detection and other processing, followed by analog to digital conversion. This part of the circuit design is the target azimuth detection circuit; after obtaining the digital signal, Its calculation and processing to get the offset, this part of the system to the floating-point DSP TMS320C6713 as the core digital signal processor, the minimum design of the 6713 system. In addition, we give the algorithm program which takes the 13 feature points as an example and uses the inverse interpolation method.
