摘      要：This paper focuses upon the novel optical conical scanning imaging working mode design for small *** kind of satellite employs only one inclined optical camera achieving wide-swath imaging via a rotational motion about the nadir axis either by the camera or by the *** working modes are designed,i.e.,high-speed rotational mode,low-speed rotational mode,and variable-speed rotational *** the high-speed and low-speed working modes,the camera rotates at a constant speed and the corresponding angular velocity is derived under the consideration of guaranteed coverage and minimized *** improve the system performance,an enhanced working mode taking advantages of both the high-speed rotational mode and lowspeed rotational mode is *** in this variable-speed rotational mode,the camera rotates slowly to get high-quality pictures when it works,while it rotates rapidly to reduce the energy consumption and save the storage during which period the camera is turned off to minimize the *** these working modes are illustrated in detail,and numerical simulation tests are conducted to validate their effectiveness.
