Bistatic Doppler Estimation Based on Extremely Large Aperture Arrays
Future networks are expected to leverage joint communication and sensing (JCS) enabled by advances such as extremely large aperture arrays (ELAAs) and high-frequency operations. These technologies introduce significant near-field propagation effects, which can be exploited to enhance sensing performance. This paper investigates velocity sensing through Doppler analysis in bistatic radar systems. By leveraging ELAAs, we demonstrate how velocity components can be accurately estimated. Performance bounds are derived to quantify the influence of system parameters and bistatic geometries on Doppler-based velocity estimation. The results highlight the advantages of bistatic sensing with ELAAs, offering new insights to drive the design and optimization of JCS for 6G networks.
