| Abstract: | Basic principles of 8 element DBF phased array radar, whose afmplitude and phase control is based on DDS technology, are intorduced in this paper. Each subsystem such as antenna, digital T/R module, system software is discussed. The operation process and calibration process of the radar system are also covered. In same time, the measured amplitude and phase errors of transmitting channels, transmitting patterns, transmitting nulling patterns and receiving pattern after error calibration are provided. |
