浅析ALENIA SIR-M二次雷达PHADE组件故障引起的目标偏移

Analysis of the target deviation of ALENIA SIR-M secondary radar caused by PHADE component failure

ALENIA SIR-M单脉冲二次雷达已经投产近20年,目前仍然在空中交通管制系统中发挥重要作用。但由于器件老化、性能下降、备件紧缺,给一线技术保障人员提出了很大的挑战。文章介绍ALENIA SIR-M二次雷达使用到的单脉冲测角技术,然后对PHADE组件故障引起的目标偏移现象进行简单分析并提出解决办法。

The ALENIA SIR-M secondary radar has been in production for nearly 20 years and has still played an important role in the air traffic control system.However,the first-line technical support personnel of the radar are facing great challenges due to the aging of devices,declining performance,spare shortage.This article introduces the single-pulse angle measurement technology used by ALENIA SIR-M secondary radar,and then simply analyzes the target deviation caused by PHADE component failure and proposes a solution for the problem.
