An integrated MMW radar system for outdoor navigation

The design of a MMW radar sensor for mobile robot outdoor navigation is presented, which is able to operate robustly even under adverse weather conditions. This sensor has a range of approximately 200 metres and uses a linear array of receivers and wavefront reconstruction techniques to compute range and bearing of objects within the field of view. Currently sensor design and hardware fabrication have been completed and the sensor is being integrated with other vehicle systems. Signal processing techniques are discussed and results obtained from simulation and the real sensor are presented.
