Real-Time Imaging Microwave Interferometric Radiometer Using Three-Level Digitization Threshold Fast Estimating Method

Microwave interferometric radiometers are widely used in measuring soil moisture and sea salinity. However, achieving high-accuracy measurements of geophysical parameters requires complex correction and inversion processes, which existing MIR cannot image in real time. This study using three methods for fast estimation of the quantization threshold, enabling real-time computation of correlation coefficients and simplified calibration for real-time imaging. In this paper, we demonstrate real-time imaging through a one-dimensional prototype.
