针对无线电测量信息经各项系统误差修正后还存在误差残差的现象,为使弹道结果更加精确可靠,详细分析测量信息中包含的各种误差残差对计算弹道的影响,对来自不同源的误差残差进行合理的线性解耦处理,采用有限变分技术,建立测量信息的误差残差对弹道计算的解析关系,用该方法进行仿真分析,结果表明,该方法能较好的反映残留误差对弹道的灵敏度影响,为设备如何消除系统偏差提供充分依据,有效提高数据处理结果的精度。

Aiming at the phenomenon of residual error after system error correction for radio measurement information, for optimi-zation of trajectory result, the effect of each residual error on trajectory calculation was analyzed in detailed, residual errors from different source were linearly decoupled, the analytic relation of measurement information's residual error to trajectory calculation was set up by limited variation technique The above-mentioned ways were used for analyzing the true metrical data and the way was found can better reflect the sensitivity effect of residual error to trajectory, sufficiently supporting equipment to eliminate system bias and improve the precision of data processing result effectively.
