"The analysis of Precision of Domestic Radio System Short-Range Navigation and Landing in Microwave Band"

"The results of precision evaluation of the range measuring channels for short-range navigation and landing systems are presented. The evaluation is performed taking into account the features of the hardware implementation of onboard and ground equipment of short-range navigation systems, the radio navigation signal processing algorithms, the format of the signals of the range measuring channels as well as interference environment. The influence of reflections from local objects is considered as well as signal distortions in onboard receiver and inaccuracies in the ground range-azimuth beacon. Taking into account these interfering factors, the overall error in the range finding is determined as well as the part of the error introduced by the equipment of the ground range-azimuth beacon."
