摘要: Near-space is recognized as the atmospheric region from 20 to 100 km above Earth's surface. vehicles offer several advantages compared low earth orbit satellites and airplanes because near-space are not constrained by orbital mechanics fuel consumption. These provide potential for future remote sensing applications, but little related work has been published. This paper explains what how it should be exploited applications. A vehicle-borne synthetic aperture radar (SAR) with reflector antenna digital beamforming on receive proposed high-resolution wide-swath (HRWS) sensing. The system configuration, signal model, imaging scheme, performance, nadir echo suppression investigated. An example conceptually designed, along its performance analysis. It shown that SAR can operate high flexibility reconfigurability, thus enabling a satisfactory HRWS performance.
