Abstract

The article analyzes in details the double-channel Doppler direction finder. The main purpose of the study is to identify the important features of the direction finder operation, to obtain relations, adequately reflecting the processes in it, and to make recommendations on information about the angular position of the target. The article specifies the description of the signal at the output of the rotating antenna. When analyzing the direction finder, we have taken into account the impact of instability of the amplitude and phase characteristics of line channel, time delays of devices that make up the direction finder. These helped clarify the output voltage of the direction finder and to formulate requirements for its components. The analysis proved that the time delays of line channels, the instability of their characteristics do not affect the measurement result. It is proved that the presence of time delays of other devices of the direction finder leads to additional phase shifts in modulating oscillation of a processed signal, which can affect the value of the angular position of the object from its actual value. It was shown that the direction finder could run on both odd and even harmonics of the frequency of rotation of an antenna. The obtained results reveal a number of important features associated with the choice of mode of the direction finder operation that helps optimize its performance
