The digital radiometer detector (DRD) is a digital signal processing detector, of which the essential elements hardware consist of a high-speed, high-resolution analog-to digital converter (ADC). A practical ADC will have an uneven step size (differential nonlinearity) between quantization thresholds, and changes the probability distribution of the sampled data and further distorts the input signal,...
Synthetic aperture radiometer has the potential to meet the spatial resolution requirement of passive microwave remote sensing from space. A one-dimensional prototype of aperture synthesis radiometer at millimeter wave band is introduced in this paper. It contains 16 antenna elements, 16 receiving channels, 16 ADCs, and image reconstruction part. Error correction is made in the image reconstruction...
