“先进光学卫星”是搭载先进陆地观测卫星（ALOS）的光学传感器的后续卫星，在日本宇宙航空研究开发机构（JAXA）发射的陆地观测卫星系列中被称为“ALOS-3”。与ALOS上搭载的全色立体测绘遥感仪（PRISM）相比，它将实现0.8米的地面分辨率提高约三倍，同时保持70公里的宽带。虽然该传感器不像“棱镜”那样配备多个传感器单元，实现全天候沿轨道立体观测，但它将能够利用距离最低点60度范围内的大型身体指向能力获取立体图像。数字表面模型（DSM）将作为ALOS-3任务的高水平产品之一，对立体图像进行处理。本文报道了一种利用ALOS-3立体图像生成DSM的发射前仿真方法。
The "Advanced Optical Satellite" is a follow-on satellite of the optical sensors onboard the Advanced Land Observing Satellite (ALOS) and is called "ALOS-3" in the series of land observing satellites launched by Japan Aerospace Exploration Agency (JAXA). It will achieve approximately three times higher ground resolution of 0.8 m while keeping the wide swath of 70 km as compared with its preceding Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the ALOS. Though the sensor does not equip with multiple sensor-units which achieve the full-time along-track stereo observation like the PRISM, it will be able to acquire stereo imageries by using a large body-pointing capability within 60 degrees from nadir. The digital surface model (DSM) is expected to be processed from the stereo imageries as one of the high-level products in the ALOS-3 mission. This paper reports on a pre-launch simulation of the DSM generation from the ALOS-3 stereo imageries.
