Description

Technical Field

[0001] This utility model belongs to the field of radar technology, and specifically relates to a radar that uses a shell to achieve anti-interference. Background Technology

[0002] Radar is a technology and device that uses electromagnetic waves to detect targets. It determines the target's distance, angle, speed, and other characteristics by emitting radio waves and receiving signals reflected from the target. Here are some key points about radar. During operation, the internal electronic components of radar are susceptible to external interference, leading to problems such as: 1. In the presence of strong clutter or artificial interference, the target echo signal may be submerged and difficult to distinguish, resulting in a reduced detection range or even complete loss of target tracking; 2. Interference sources introduce additional noise components, blurring previously clear features and affecting the accuracy of estimating parameters such as target position and speed; 3. When faced with large-scale interference of multiple types simultaneously, traditional algorithm structures may become paralyzed due to insufficient computational resources and be unable to continue normal operation. Furthermore, in radar anti-interference measures, the outer casing often serves only as a protection for internal electronic components, and insufficient sealing at the casing joints can affect actual anti-interference performance.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
