An experimental radar device for the observation of the earth from an aircraft

Remote sensing data in the optical, infrared, and microwave range have become indispensible for a number of scientific investigations. The importance of the microwave sensor has increased in recent years in connection with its all-weather capability, which is vital for the geographical latitudes of Central Europe. Current limitations regarding the use of the microwave sensor are related to technological problems. In connection with the clearly recognized European need for a suitable microwave sensor, West Germany wants to improve the technology related to the microwave remote sensing of the earth. It is planned to provide for the users an operational satellite sensor system during the mid-1980s. A program for implementing this objective is being prepared. The first step taken in this connection was the design of a cost-efficient experimental radar device for the observation of the earth from an aircraft. Basic information regarding the observation of the earth with radar is considered and a survey is provided regarding the performance of the new device, taking into account the first results.
