Reliability and validity have always been the most important criteria in micro-satellite designing. Beside this, other important factors such as miniaturization, fault tolerance, data rate, redundancy and power consumption should also be fulfilled by satellite systems. The limitation to reliability and redundancy is the interdependent links of subsystem and(More)
Multipath effects are investigated on inverse synthetic aperture radar (ISAR) image reconstruction of ships with rectilinear motion in different sea state. First, the generalized problems of multipath propagation in radar application are formulated. After a brief review of ISAR imaging principles, multipath propagation effects on ISAR imaging are(More)
To address the issues of single event upsets caused by radiation in outer space to micro-satellites, we proposed a novel reconfigurable on-board computer system with three soft core CPUs inside the Field Programmable Gate Array(FPGA), with the function of error detecting and restoring configuration. Two of the soft core CPUs act as the central processing(More)
The research scope of grey relational analysis has not been developed in recent years, and the exiting GRA models are all based on three perspectives, including distance perspective, slope perspective, and area perspective. Under this situation, a novel model called grey relational analysis based on angle perspective (GRAAP) was developed in this paper for(More)
Satellite flying formation missions are being prepared by more and more aerospace centers for the potentials they have. They also bring challenges like clock synchronization. This paper introduces a dedicated hardware device, General Cell (GC), which is a general micro-platform of spacecraft C&DH system, fully fits to formation flying space(More)
This paper presents the application of the emulated bistatic radar (EBR) geometries to 3D interferometric inverse synthetic aperture radar (In-ISAR) imaging techniques. The EBR is introduced into the height estimation of a target in order to reduce the expenses and complexity associated with standard interferometric processing systems, while the In-ISAR(More)
