Abstract
Passive operation is an important operational concept for future airborne radar platforms. Successful target detection requires an understanding of the underlying clutter statistics in order to set the detection threshold accurately. In addition, clutter statistics are important for modelling of passive radar performance and simulation of passive bistatic radar to aid in the development of new target detection algorithms. In this chapter, the clutter statistics of data from an airborne platform are studied over a range of bistatic geometries and receive polarisations. The illuminator is a digital video broadcast-terrestrial (DVB-T) station and the collected data spans both ground and maritime regions. The key contributions in this chapter include a study of amplitude statistics using a number of common distributions, understanding the impact of the reference signal quality and an analysis showing the distribution accuracy as the integration time and bistatic range varies.
