This article presents analysis and parametrization of the bistatic ground clutter which is important from the point of view of the modelling/generating of bistatic clutter, and subsequent developing of the new suppression techniques. The analysis of the bistatic radar has been an active area of research for almost a decade now. The paper includes analysis of bistatic land clutter trials, run in the Czech Republic, specifically in Pardubice city. First, the theoretical part of bistatic radars and models of bistatic clutter is described. The bistatic clutter is measured by a passive radar system developed by the ERA a.s. company. The analysis of bistatic clutter starts with pre-processing techniques such as antenna virtual rotation and suppression of direct signal. The residuals of the signal are used for bistatic clutter analysis and consequently used for determination of bistatic clutter parameters. These parameters are replicas of individual channels, power of replicas, etc. The output is the development of universal analysis software for bistatic clutter that is used for bistatic clutter generation, mandatory for developing suppression techniques.
