| Abstract: | The difference between three "availability" of the sky wave radar are discussed in this paper. It is emphasized that the ionosphere, propagation medium of this new radar system, is a type of particular medium, which is non uniform anisotropic, dispersive and random, and the propagation channel of the radar is nonlinear and time varying channel, and the operational environment of the skywave radar is very complicated. The study method and its examples of channel availability of the skywave radar in low latitudes are presented. The calculated methods and examples of the time availability of the skywave radar system which possesses given equipment capability for detecting different targets are described The influence of environment noise on the time availability is pointed out. |
