根据美国“航空周刊及宇宙技术”杂志1979年第1期及1978年国际雷达会议录报导:RAT-31S三座标雷达是意大利赛勒尼亚公司于1973年开始研制的,1978年投入生产,计划生产20部,予计八十年代初服役。该雷达的设计旨在滿足八十年代的战术技术要求,它的主要性能特点如下: 1)工作于S波段,有校宽的带宽,带宽可变化13％。 2)采用4×4米的相扫平面阵列天线。在仰角产生三个堆积波束,用铁氧体移相器和二极管移相器来完成独立的扫描;方位波束用一组线性阵列辐射单元来完成扫描,每个
According to the magazine “Aviation Week and Universe Technology”, 1979, No. 1, and the International Radiological Meeting 1978, the RAT-31S Radar is developed by the Italian company Serina in 1973 and put into production in 1978, Plan to produce 20, expected to serve in the early 1980s. The radar is designed to meet the tactical technical requirements of the 1980s. Its main performance characteristics are as follows: 1) Working in the S band, there is a wide bandwidth and the bandwidth can vary by 13%. 2) using 4 × 4 m phase sweep plane array antenna. Three buildup beams are generated at elevation angle, and the independent sweep is done with ferrite phase shifters and diode phase shifters; the azimuth beam is scanned with a set of linear array radiating elements, each
