Measurement accuracy analysis for on-board measuring devices

The problem of accuracy and reliability of measurement results of on-board measuring radio-electronic equipment is considered. The analysis of the accuracy of the measurement of the range by a radio frequency range station placed on a mobile object under the influence of interference is carried out. We show that there is a nonlinearly increasing dynamic error if the optimal filter was constructed without taking into consideration of the elements nonideality. So precision of distance measurement of mobile radio-range station depends on the interference. This example emphasizes the importance of the quality problem of components used in onboard equipment and establishing tolerances for component parameters.
