摘要
针对传统CCD测角系统在野外环境下抗干扰能力弱的问题,本文提出了提高野外环境下CCD准直测角精度的一整套方案。该方案从测角系统的各个环节入手,分析了各自技术要求,在不同环节分别采取相应的技术措施,主要包括半导体激光器功率稳恒控制、光谱匹配与窄带滤波、CCD自动变扫描控制和CCD倍频插值细分等。实验结果表明,通过上述技术措施可以很好的加强野外环境下CCD测角系统的干扰能力,有效提高了系统测量精度。
Aimed at the weak anti-interference ability of traditional angle measuring system in the open field, a set of complete plan was proposed to enhance the angle measuring accuracy of CCD alignment in the wild environment. Beginning with each segment of angle measuring system, the plan analyzed various technological principles and also adopted corresponding technological steps in different segments, which mainly included technologies of semiconductor laser power constant control, optical spectrum matching and narrow-band filtering, CCD automatic changeable scan control and CCD frequency doubling interpolation subdivision, etc. The test result proves that the above mentioned method can enhance the anti-inference ability of CCD alignment in the wild environment and the system measuring accuracy.
