MICROWAVE PHASE MEASUREMENTS ON THE ACTIVE SWEPT FREQUENCY INTERFEROMETER RADAR SYSTEM
Abstract
Many microwave systems currently in operation require strict control of the phase and gain characteristics of the system. The Active Swept Frequency Interferometer Radar System transmits a linear FM ramp to obtain range and angle information. If the transfer characteristics of the system transmission and receiving networks possess constant gain and linear phase variation over the signal frequency band, the linear FM ramp signal will pass through the system undistorted. If, however, the system possesses inadequate phase linearity, the signal suffers phase distortion which results in a loss of signal amplitude and range resolution. The various methods of measuring phase linearity and associated errors are discussed, as well as results of actual tests conducted on the components of the experimental Active Swept Frequency Interferometer Radar. These tests include results with passive components, as well as active components such as TWTs and high power klystrons.
