[0050] Example
[0051] 1) Experimental equipment:
[0052] ①Microwave thermal radiation array receiving system, the specific parameters are as follows:
[0053] Working band: 8mm band
[0054] Number of antenna array elements: 16
[0055] The array adopts 1 times the wavelength minimum redundant array arrangement: the maximum baseline length is 90 times the wavelength, and the length is 741.2mm
[0056] System resolution: 0.011rad
[0057] ②Two solid noise sources:
[0058] In the experiment, one of the solid noise sources was used to replace the artificial target because they have the same signal characteristics. Another noise source serves as an external correction source. Solid noise source parameters: operating frequency is 34.5-37.5GHz, super-noise ratio is 23dB.
[0059] 2) Experimental design:
[0060] Place a solid noise source as an artificial target at a distance of 675cm from the array radiometer system at an angle of -2°; turn on the noise source to measure the output o...
