本文提出了一种新的测距信号形式——时分轮换单边带测距信号。此种信号形式所构成的测距系统,可以实时测量和消除由于测距系统主信道测距音时延变化所引入的测距误差。本文论证了新方法的原理,导出了工程计算公式,给出了计算结果。理论分析表明,本方法具有提高测距精度的潜力。 This paper presents a new form of ranging signal - time-sharing single-sideband ranging signal. The ranging system composed of such signal forms can measure and eliminate the ranging error caused by the variation of the main channel ranging sound delay in the ranging system in real time. This paper demonstrates the principle of the new method, derives engineering calculation formula and gives the calculation results. Theoretical analysis shows that this method has the potential to improve the accuracy of ranging.
