ABSTRACT

To calculate the azimuth angle and elevation angle of the HF echo arrival angle, based on the calculation of one-dimensional single baseline measurement, this paper proposes a method to calculate the arrival angle of HF echo using two-dimensional equal length single baseline measurement. Methods, and for the characteristics of HF propagation, the measurement error caused by Doppler frequency shift and phase error was analyzed, and the two main error reduction methods were proposed
