Abstract


Space rendezvous and docking technology , space technology is one of the most complex , the largest and most variable parameter control operating techniques , but also the key to the control of space research topic . Ground semi- physical simulation is an effective way to get the high reliability , economy , and high-performance rendezvous and docking system . Domestic rendezvous and docking semi- physical simulation are mostly concentrated in the final approach phase , the distance close to the segment , and in close proximity to the segment that less space rendezvous COSCO semi-physical simulation . Before the design space rendezvous COSCO ground semi- physical simulation method , we study the distance scale simulation . In order to reduce the measurement error of the space rendezvous COSCO segment measuring element simulation of ground equivalent method of measuring element in the ground in the semi- physical simulation . The design of a millimeter-wave radar the measurement simulation methods : in the millimeter-wave radar echo signal analog equipment analog millimeter-wave radar echo signal is installed on the target simulation aircraft offset fed single reflector compact non- plane wave plane wave is converted to approximate the far-field conditions . The method of simulation according to the given compensation measures to compensate , the error can be ignored . Study the CCD ( Charge Coupled Device , Charge-Coupled Device ) camera in space rendezvous distance segment ground in the semi- physical simulation method and error causes . Caused by the relative motion between the analysis of the camera and the target aircraft like shift error for the measurement . Deduced according to camera parameters and the state of motion to strike like a shifting error formula to measure the the error image quality image motion and image modulation function . Design a space rendezvous and docking ground semi- physical simulation experiment method and can complete the experiment and analysis of the distance contraction than the simulation error simulation experiments .
