This article provides a systematic introduction to the key considerations for selecting bridge collision avoidance radar, covering critical dimensions such as detection range, measurement accuracy, device reliability, and operational maintenance convenience. It aims to assist in making a scientifically informed choice of the appropriate model, thereby enhancing the safety protection capabilities of bridges.

Radar operating frequencies extensively cover the electromagnetic spectrum, typically ranging from 220 MHz to 35 GHz, though they can extend as low as 2 MHz or as high as 94 GHz. While engineering implementations vary significantly across different frequency bands, the core principle remains the same: emitting electromagnetic waves and receiving their reflections from targets to enable detection and positioning.

This article systematically elaborates on the structural composition and functional characteristics of border and coastal defense radar, with a focus on analyzing its multiple technical advantages in security applications. These include wide-area surveillance, multi-target tracking, high-precision detection, and user-friendly operation, making it suitable for all-weather intelligent protection of borders, airports, and critical infrastructure.

The S, C, and X-band phased array weather radar developed by China Electronics Technology Group Corporation enables efficient monitoring of severe weather events such as storms and heavy rainfall, significantly enhancing early warning capabilities. This technology is also applied in civil aviation for low-altitude wind shear detection, greatly improving scanning speed and resolution, thereby strongly ensuring aviation and meteorological safety.

Drone detection radar technology offers advantages such as high-precision reconnaissance, low cost, and strong reliability. It can be rapidly deployed and adapted to complex environments, and has been widely applied in military, environmental monitoring, industrial, and urban security fields, providing critical support for intelligence gathering and smart decision-making.
