Evaluation of bias errors in positioning a radio transmitter with a lot of interference waves

摘要

It is frequently observed in positioning a radio transmitter that interference waves cause bias errors. Since interference depends on physical conditions of wavelength, errors have been discussed case by case. In this paper we introduce the worst interference wave in the class of power less than that of the signal. Analytical evaluation of the worst errors in positioning by the maximum likelihood estimation for arrays are presented and verified numerically.
