Abstract
The DLR Radar-System SIREV is a forward looking airborne radar with a fixed mounted antenna at the fuselage of an aircraft or a helicopter. It is able to operate at different frequencies from L-band up to Ka-band and delivers high quality radar images of a flight sector ahead the airpath. The real time generated radar images look very similar to optical images. Depending from the application it can also include a 3D vision as well as information of ground elevation (e.g. obstacles). Due to the all-weather capability of the system and its ability to present radar images very similar to optical images either as top view (mapping mode) or as pilot view (central perspective), the system is especially qualified for: (1) navigation support to the pilot under IMC flight conditions; (2) autonomous landing approaches; (3) taxi support at the ground; (4) dropping of goods or airborne troops. Currently the system is under development. First simulations with data of the SAR system of DLR were performed. The expected image quality and the resolution of the SIREV system can presently not be achieved by any other system.
