Popis: There has been a recent surge in activity related to bistatic synthetic aperture radar (SAR) systems. This is, in part, due to recent advances in hardware making such systems more attainable and the fact that the approach itself has the potential to provide the following unique properties: 1. Defeating counter-measures (such as jamming). 2. Improving detection performance by reduction of 'spiky' clutter. 3. Investigation of complex radar phenomenology (e.g. analysis of complex scattering environments, such as the inside of buildings). A SAR image is typically formed by having a moving radar system (e.g. on a spacecraft or an aeroplane) which transmits a series of pulses illuminating an area of the ground and records the energy reflected from the ground. It is then possible to combine these recorded reflected pulses into a map of radar cross section (RCS) as a function of 2D position within the illuminated area.
