A portable primary radar for general aviation

A detailed situation awareness of the local environment is essential for safe flight in General Aviation. When operating under Visual Flight Rules, eyesight is crucial for maintaining situation awareness and objects may be overlooked. Technical solutions such as Flarm have been sought, but they only work on a basis of co-operation: obstacles...

Validation of GPS by Ground Scanning Radar Generated with an on-board wide-angle FMCW radar for General Aviation

Many pilots in General Aviation use electronic add-ons aids in flight, which rely on satellite navigation information. This navigation information is often a single point of failure which is undesirable since the pilot relies on the information. This paper presents the results of research whether a novel mobile radar station can be used to...

Estimation of Flight State with a Collision Alert Radar Based on FMCW Reflections of the Landscape for General Aviation

Although the main goal of a newly developed Collision Alert Radar is to observe airborne targets, it was found that reflections of the ground are received by the radar. The radar is carried on board of the aircraft, and the ground reflections may be used to detect flight information with respect to the terrain, something which is not possible...

Object Tracking in Images of an Airborne Wide Angle FMCW Radar

Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...

Overview of NLR Free Flight Project 1997 -1999

NLR has investigated the feasibility of Free Flight concepts with airbome separation during several years of research in collaboration with NASA, the FAA and the RLD (Dutch Civil Aviation Authorities). Issues that have been addressed are: • conflict detection & resolution methods • complex conflict geometries • pilot workload • pilot...
