Short Range mm-Wave SAR for Surveillance and Security Applications

Inhalt:
Recent advances in the area of automotive radar led to the development and availability of integrated components (MMICs) in the millimeter-wave range. Besides the automotive sensors also industrial and security applications can take benefit from these components. For example a distributed system for runway surveillance consisting of several mechanically steered broadband sensors has been proposed recently . To evaluate SAR as another interesting candidate for this kind of applications, a broadband demonstrator has been developed at 77GHz. Combined with monostatic or digital beam forming (DBF) sensors, the basic SAR modes such as Stripmap SAR and Spotlight SAR have been implemented successfully. Additionally azimuth SAR processing was combined with DBF in elevation. This configuration allows the three dimensional imaging of scenarios.
