Abstract

The invention relates to the technical field of SAR (Synthetic Aperture Radar) antennas, in particular to an antenna system, which comprises a plurality of working equipment groups arranged at intervals along a first direction, any working device group comprises a plurality of working devices, the working devices are active devices or passive devices, and the working devices are arranged at intervals in the second direction; wherein at least one side of at least part of the working equipment is provided with a first heating device; under the condition that the same working equipment group comprises active equipment and passive equipment, for the same working equipment group, the total number of the first heating devices arranged on all the passive equipment is greater than or equal to the total number of the first heating devices arranged on all the active equipment; for different working equipment groups, the number of the first heating devices arranged in the working equipment group containing a large number of passive equipment is larger than or equal to the number of the first heating devices arranged in the working equipment group containing a small number of passive equipment. According to the scheme, the problem of soaking of the SAR antenna is solved.

Description

Technical field [0001] The present application relates to the field of SAR antenna technology, in particular to an antenna system. Background [0002] At present, the plane array system SAR antenna is concentrated on the antenna plate, and the device on the flat panel is very sensitive to the influence of temperature, and the temperature index requirements are high, so it puts forward high requirements for thermal control. In order to ensure the imaging instructions of the antenna, the temperature of the antenna electronic device needs to be controlled in the temperature range of -25 °C ~ +45 °C. [0003] In order to facilitate transmission, SAR antennas are mostly composed of multiple independent subarrays, and the more common number is 4 to 6. During the operation of the SAR antenna, there are both temperature stability requirements and maximum temperature difference requirements between each single machine. During operation, the maximum variation of the average temperature di...
