Sensor placement for improved target resolution in distributed radar systems

Abstract

In this work we investigate rules for sensor placement as a way of improving multistatic radar system performances. We follow the approach of shaping the multistatic ambiguity function, but instead of different weighting rules and different waveforms, as studied in recent works, we consider different system geometries. We concentrate our attention on target resolution as a performance measure and present simulation results that illustrate the significance of adequate sensor placement in multistatic radar systems.

“…Figure 5 shows the map of the product M g P0BT in the ground plane. Dashed line represents the resolution ellipse: it is the locus of all points in the plane (x, y) satisfying (17). Appendix (9.3) describes the method used to compute this resolution ellipse: is the resolution in thê y direction,…”

“…The authors address the rules to select the weights for fusing multiple receiver signals in order to reach specified performances. Sensor placement in bistatic and multistatic radar systems and how it relates to the system resolution has been studied in [15], [16] and [17] by calculating the Cramer-Rao lower bounds (CRLBs) for bistatic radar channel.…”
