摘要: 以微波為探測手段進(jìn)行對地成像觀測,能夠全天候、全天時工作,在許多技術(shù)領(lǐng)域得到了重要應(yīng)用,對微波成像的新思想、新體制、新技術(shù)的探索,也是一個非?；钴S的研究領(lǐng)域。該文提出了一種新的微波成像方法,稱為微波散射成像方法,該方法可采用收發(fā)分置工作方式,工作時只需要以單色波照射待成像地域。原理性成像模擬結(jié)果表明,使用這種方法可以獲得被觀測地域高幾何分辨率和高輻射分辨率的微波圖像。

Abstract: Microwave imaging techniques which can provide all-weather, day-and-night imag-ing capability have important applications to many scientific fields. It is an active area to ex-plore new microwave imaging ideas, systems and techniques. In this paper, a new microwave imaging method for earth observation is proposed. In this method, the signal transmitter and receiver are located in different platforms, and only a monochromatic microwave is required to illuminate the earth surface. Numerical simulation results show that this method can produce a microwave image with high spatial and radiation resolutions. -
