Abstract: 

In recent years, the applications of radar have diversified from its roots in aviation and marine surveillance. Today, radar applications include weather forecasting, terrain profiling, velocity measurement, collision avoidance and satellite detection. The recent development of Multiple Input Multiple Output (MIMO) radar promises to push this technology further into applications where size, weight and power (SWAP) constraints predominate. MIMO achieves SWAP advantages by moving many of the physical elements of the signal formation and analysis into the digital signal processing, meaning an overall reduction in the amount of hardware required in a system. The research presented in this seminar will show that a combination of different beamforming techniques can be used to determine the position and magnitude of point scatterers to accurately model an imaging scene. The first stage of the research will concentrate on using spectral estimation algorithms to improve the resolution of a single image or “frame” from the radar. The second stage will be concerned with using these accurate target measurements as an input to a self-localization algorithm, which can be used to combine multiple frames of the radar together. The combination of these algorithms will allow the achievement of a radar system design engineer’s specifications of resolution and accuracy using less physical sensing elements than would normally be required. Thus these algorithms will further promote the SWAP advantages of MIMO radar, opening up new space, weight and power constrained applications in both the civil and defence fields.
