摘要：
When radar measures the aerial target, the influence of atmospheric refraction will lead to its measurement error. First, based on the principle of correction for atmospheric refraction on single station system, an algorithm correction for atmospheric refraction of passive TDOA location system is described. Secondly, the influence of atmospheric refraction correction on system error is analyzed theoretically. Finally, the actual data are processed and the systematic error of TDOA in different directions is within 10ns.The effectiveness of atmospheric refraction correction of passive TDOA location system is verified by the actual data.
