适用范围

The proposed methodology consists of deriving curves by curve-fitting the validation epfd↓ limits given in RR Table 22-1D applicable for the protection of GSO BSS systems with inclination angles less than 2.5? and for earth stations at latitudes below 57.5?. These curves, hereafter referred to as validation limit reference curves, are constructed by linear interpolation between values of epfd↓(dB) and by logarithmic interpolation between values of percentage of time for which the epfd↓may be exceeded.
