Abstract
The investigation deals with the effects of phase and amplitude differences between two coherent point source radiators on the tracking behavior of a monopulse radar. The tracking functions of the radar is modelled in a single plane, containing the two point sources located at a finite distance from the radar antenna. The complex illumination of the antenna aperture by the point sources and the resulting monopulse sum and difference antenna responses are derived, including the effects of finite range. The monopulse discriminator characteristic is formed using the antenna responses. A set of calibration curves are presented which show the transfer of the tracking point of the radar from one source to the other as the phase and amplitude differences between the sources vary. A computer program is presented to calculate the effects of phase and amplitude variation on the tracking point of the radar in the general case. TRUNCATED
