- W4366308462 abstract "This paper is concerned with the coherent integration of multistatic radar data for the purposes of maximising spatial processing gain for enhanced detection, location estimation for improved tracking, and target imaging for recognition and classification. A multistatic radar system here is defined generally as a set of multiple bistatic transmit-receive pairs, suitably synchronised in their combined operation. The underlying principle is the exploitation of aperture to achieve higher spatial resolution than is possible based upon bandwidth alone. The spatial resolution achieved is configuration-dependant and a system is configured appropriately for an application of interest. Starting with a coherent multistatic radar system signal model, an inverse problem is formulated and solved using sparse estimation with a fixed spatial grid. This provides approximate estimates for target point scatterer numbers and locations which may then be refined using an adaptive off-grid estimation technique. This allows the point scatterers in the signal model to adapt their locations to better fit the observed data and maximise coherent gain. Results are given in two dimensions for 5 co-planar transmit-receive pairs." @default.
