Abstract

The invention belongs to the technical field of a radar system and especially relates to an all-solid-state X-band airport surface detection radar and a working method thereof. The airport surface detection radar adopts a dual-redundancy system structure; a servo drive subsystem realizes dual-redundancy connection under control of a monitoring unit A and a monitoring unit B; each transmitter adopts a high-power solid-state amplifier; and each receiver adopts a large dynamic modularized digital receiver, and supports single-channel frequency agility and frequency diversity working modes. A transmit-receive subsystem A and a transmit-receive subsystem B realize dual-redundancy connection under the control of the monitoring unit A and the monitoring unit B. A signal processing subsystem A anda signal processing subsystem B realize dual-redundancy connection under the control of the monitoring unit A and the monitoring unit B. The radar system has a function of whole-course supervision offixed and moving targets and rainfall distribution, and supports all-weather and all-day uninterrupted unattended operation.

Description

technical field [0001] The invention belongs to the technical field of radar systems, and in particular relates to an all-solid-state X-band airport surface monitoring radar and a working method thereof. Background technique [0002] The all-solid-state X-band airport surface surveillance radar is a short-range high-resolution radar that uses a high-speed rotating narrow-beam antenna to monitor various fixed and moving targets on the airport surface in the form of real-aperture imaging. The technology is complex and the equipment is large. , high reliability requirements, is a high-tech product in the field of air traffic control radar. [0003] At present, the signal processing of X-band airport surface surveillance radar generally only adopts simple amplitude threshold processing, which cannot detect and track the targets within the radar coverage. Therefore, such products usually open windows on the runways and aprons that tower controllers focus on, and only detect and ...
