Synthetic Aperture Radar



The radar can realize the control of the radar through the link between the data transmission system and the ground equipment, or it can work automatically through the preset route and working mode.

When the system works, under the control of the integrated processing module, the antenna can receive the radiation and echo signals of microwave high-power pulses, and the beam scanning driving function can be completed under the control of the integrated processing module. The transmitting module completes the modulation and power amplification of the microwave signal, which is provided to the antenna through the transmission channels such as the annular device and the rotary joint. The antenna radiates to the designated area. The low-power RF module provides a specified transmit excitation signal to the transmitting module under the control of the integrated processing module, and performs low-noise and large-dynamic linear amplification, frequency conversion, and filtering on the echo signal sent from the antenna. The intermediate processing echo data is provided to the integrated processing module, and the integrated processing module performs functions such as A/D conversion and full-time timing, signal processing and data processing, system control management, and data communication. The control information and the carrier data from the task management system are received, and the radar status is output to the task management system, and the scout image data is output to the on-board data transmission device. The power module transforms and filters the input power provided by the aircraft to provide various power supplies required by each extension of the radar.

Each LRU is connected together via internal buses and interfaces to form a complete unit to perform specified ground detection.
