Optimal Layout of a Bistatic Radar Network

Abstract Bistatic Doppler radar networks have become in the last five years a viable and inexpensive alternative to multiple-Doppler networks. In this study, the optimization of the layout of a bistatic network is analyzed. The main parameters determining the criteria for the maximization of data quality are (i) variance of the wind component perpendicular to the one measured by the monostatic radar, (ii) received power, (iii) resolution of the sampled volume, and (iv) sidelobe contamination. A location index is defined in such a way that optimization of these four parameters can be carried out simultaneously. Two different approaches are discussed: 1) it is supposed that the location of the bistatic receiver is given and the area of high quality coverage is investigated, and 2) a region of interest is defined and the optimal location of a bistatic receiver is sought. Sidelobe contamination is a serious problem, irrespective of the receiver's location. The deployment of more than one passive receiver incr...
