K wave band receiver noise temperature test method

The invention relates to a K wave band receiver noise temperature test method. A device related in the method is composed of a K wave band receiver, a pedestal, a fixed frame, a rotary shaft, a turn table, a normal temperature black body, a rotating shaft, a U-shaped bolt, a first rotating shaft fixing board, a second rotating shaft fixing board, a first fixing pin, a second fixing pin, a slidingblock, a sliding block connection rod, a sliding guide rail, an angle fixing threaded rod, an angle fixing nut and angle fixing sliding chute. In the method, a cold load which is difficult to operateis replaced by cold air; a test device can introduce or remove a normal temperature black body load at a feed source port surface, also can discretionarily adjust the K wave band receiver and a beam direction thereof in elevation of 0-90 degrees, and can complete measurement and calculation of noise temperature of the receiver in combination with sky brightness temperature corresponding to the K wave band under the current
