There is an increasing interest in operating radars in bistatic configuration, especially in military and stealth applications, to exploit the covert nature of bistatic receivers. Given that a radar’s detection performance is limited by the vast amount of natural and man-made clutter, rather than noise, it is imperative to design reliable detectors. In order to design such detectors, the statistical characteristics of the clutter need to be taken into account. In this thesis, experiments were carried out in the X-band to gather land clutter data in simultaneous monostatic and bistatic configurations. The data so gathered was processed and analyzed to evaluate the statistics of bistatic land clutter and to understand their variation as a function of bistatic angle. Comparison of the bistatic clutter statistics to the monostatic counterparts were also made. The amplitude statistics show that for bistatic angles between 2° and 30°, clutter fits the log-normal distribution, with µ varying between 0.95 and 1.35, and a nearly constant σ of 0.75. For bistatic angles 14° and lower, the clutter is also well modeled by a K-distribution with shape parameter between 1 and 3; and also by Weibull distribution with shape parameter between 1.4 and 1.7, scale parameter between 3.6 and 4.5. The low bistatic angle case tends to the monostatic case. The monostatic clutter, was also best modeled using Weibull and the K-distributions, with mean shape parameters of 1.55 and 2.7 respectively, and mean Weibull scale parameter of 4.4. The shape parameter for the K-distribution and the Weibull distribution were lower for higher bistatic angles and tended to the mean value of the monostatic shape parameter as the bistatic angle was reduced to the monostatic case suggesting that the bistatic clutter is spikier than the monostatic.
