Example Embodiment
[0016] A microwave window of a microwave radiometer calibration source includes: a cone-shaped gradient array 1, a cone-shaped hollow gradient array 2, and a fastening frame 3.
[0017] The tapered hollow gradient array 2 is composed of 2×n subunits. The sub-units are conical or square cone-shaped, and are made of polystyrene with the same cubic shape. On the sub-units, there is a semi-hollow structure that is complementary to the conical tip of the microwave radiator. The conical tip of the microwave radiator The half of the split is placed in it. The two sub-units are put together to form a complete complementary structure with a microwave radiator cone wedge, and are in close contact. The cone-shaped hollow structure formed by the two sub-units is conical or pyramidal.
[0018] The tapered gradation array 1 is integrally processed and formed by a piece of polystyrene, and the outer contour is rectangular. The tapered array faces outward, and the subunits of the tapered gradie...
