Abstract

Abstract

This article presents a measurement on the testing environment of an airship lifting platform in real test range scene and moderate weather condition. The results show that the heading azimuth of the airship is more stable under fixed orientation flying mode than under fixed flight path mode, while the elevation and rolling angular stabilities under the two flying modes are almost undistinguishable. Statistical analysis proves that the equipped antenna stabilizing platform can isolate the carrier's angular shake as high as ±10° and continuously control the antenna beam axis to aim at the ground target with error within ±1°. The 20-40 km distance tests show that the airship carried receiving antenna with 4.5° beam width suffered a 1 dB gain loss and ±1 dB signal level fluctuation under head-on flying path, while the results degenerate to 2.3 dB gain loss and ±3 dB signal level fluctuation in lateral flying path. The article also presents some testing results about the airship lifting platform's EM scattering environment rooting from its metal structure as well as the test range's rough ground.
