hi my name's Ian Whithouse I'm a professor of applied art observation at the University of Edinburgh and I'm an expert in radar remote sensing if you want to learn about radar remote sensing one of the things you have to realize is that the history of radar remote sensing is very different from everything you've learnt about optical and visible remote sensing if you take an object like a mobile phone there's a camera in the mobile phone and the history of that camera as a remote sensing device goes back to the 19th century and the invention of
photography and then color photography and then infrared photography and then digital scanners and that history took those instruments and put them onto balloons and aircraft but there's another remote sensing device in this smartphone and that's the ability to detect radio waves or microwaves and the history of microwave remote sensing which is vital to understanding how radars work goes back to the early part of the 19th century and understanding that the history of radar had almost no influence whatsoever of the history of optical and camera and photography development
