为了成功部署航空监视系统，在覆盖设计中选择合适的路径损失模型是非常重要的。飞行实验是评估路径损耗模型的传统方法，而利用机会目标对1090- mhz扩频信号进行被动测量是一种新的补充方法。这封信探讨了1090es测量的可行性，以评估航空路径损失模型。首先，去除使用两个应答器天线的交替传输的影响，提取传播信道的影响。然后，将飞行实验中的测量结果与自由空间路径损失给出的参考值进行比较，以表明使用1090 ES的相关性。
For the successful deployment of the aeronautical surveillance systems, it is important to select the appropriate path loss model that is used in the coverage design. While the flight experiment is a traditional approach to evaluate the path loss models, the passive measurement of the 1090-MHz extended squitters (1090 ESs) broadcast by target of opportunity is a new complementary approach. This letter examines the feasibility of the 1090 ES measurement for evaluating the aeronautical path loss models. First, the effect of the alternate transmission using two transponder antennas is removed to extract the effect of the propagation channel. Then, the measurement result during the flight experiment is compared to the reference values given by free-space path loss in order to show the relevance of using the 1090 ES.
