Other AbstractRecently ,applications f rom atmosp here ,ocean and land soil moist ure have required higher and higher spatial resolution for passive microwave remote sensors.However ,if we use the conventional technology ,once the spatial resolution reaches a certain level,the small resolution cell will limit t he sensitivity of t he bright ness temperat ure measurement due to very short integration time at each of t he cell.In t his paper ,a new technology,so called interferomet ric radiometry or synt hetic apert ure radiomet ry,is summarized. While the basic principle is int roduced,t he author stried to explain it in a different way f rom t he point of view that every target or dist ributed scene has characters in t heir f requency domain pict ures. What the new technology does is ,in fact,not to measure the scene in it s original spatial domain but to measure it in it s frequency domain by a sampling device called two-element interferometer.From t his point of view ,the new technology appear s more systematic and clear to understand. While the imaging systems are summarized ,the aut hors emp hasize more on the 22D clock rotation sampling system wit h associated image ret rieval algorit hm ,called t he Pseudo Polar Grid Met hod ,which bot h were developed by the authors.
