Abstract

The invention relates to a low-altitude warning radar subarray. The low-altitude warning radar subarray comprises an antenna linear array, an antenna frame, a combined dynamic sealing ring, a T / R assembly, a frequency synthesis assembly and a fan. The T / R assembly, the frequency synthesis assembly and the fan are installed inside the antenna frame. The antenna linear array is installed outside theantenna frame. The combined dynamic sealing ring is connected to the interface of the antenna linear array and the antenna frame in a sleeving mode, and comprises a first sealing ring and a second sealing ring, wherein one side of the first sealing ring is attached to the antenna linear array, one side of the second sealing ring is attached to the antenna frame, and the other side of the first sealing ring and the other side of the second sealing ring are combined to form a flow guide groove. The low-altitude warning radar subarray realizes the sealing of the interface of the antenna linear array and the antenna frame. Moreover, the combined movable sealing ring for sealing the interface of the antenna linear array and the antenna frame is convenient to mount and dismount, and can be repeatedly used.

Description

technical field [0001] The invention belongs to the field of radar technology, and in particular relates to a low-altitude warning radar sub-array. Background technique [0002] At present, the "low, slow and small" target activities are becoming more and more frequent, posing a serious threat to national air defense security. "Low, slow and small" targets are small in size, slow in speed, and have stealth characteristics, making them less detectable. Implementing effective long-distance early warning and real-time detection and tracking of "low, slow and small" targets is an important aspect of defense and strike. The premise and foundation of the "low, slow and small" goal. Therefore, the development of low-altitude warning radar and the improvement of the air defense system's ability to detect, identify, track and dispose of low-altitude / ultra-low-altitude targets have important practical significance for improving national security. [0003] As the low-altitude target ...
