This work investigates the achievable improvements in both target localization and receiver pose estimation by deriving the Cramer-Rao lower bound (CRLB) for a multistatic radar system performing bistatic range and bearing measurements and proposes an alternating weighted least-squares algorithm that jointly optimizes target and receiver parameters.
Abstract
Target localization in a multistatic radar system, where multiple receivers cooperate to improve target positioning accuracy, has many applications, including cooperative simultaneous localization and mapping (SLAM) and autonomous robot networks. A key challenge in these applications is the uncertainty in the position and orientation (pose) of the radar receivers due to platform mobility. This work investigates the achievable improvements in both target localization and receiver pose estimation by deriving the Cramer-Rao lower bound (CRLB) for a multistatic radar system performing bistatic range and bearing measurements. We propose an alternating weighted least-squares algorithm that jointly optimizes target and receiver parameters. Monte Carlo simulations demonstrate that the algorithm performance approaches the CRLB for low to moderate noise levels.
Target tracking is critical for applications such as automotive perception, unmanned aerial vehicle monitoring, and integrated sensing and communication. While target tracking can be achieved using multi-antenna radars, several challenges need to be addressed to ensure desirable accuracy. These challenges include the h...

A Bayesian adaptive Gaussian mixture filter is derived for single- and multisatellite relative navigation that splits mixands about the quantization set boundaries and is shown to produce accurate and consistent relative state estimates in single- and multi-inspector scenarios involving a geostationary-orbiting target.

Distributed target tracking is essential for scalable and robust sensing systems, as it enables multiple radar nodes to cooperatively estimate a target state without relying on a centralized fusion center. In this paper, we present a fully distributed framework for single-target tracking in frequency-modulated continuo...
It often occurs in multistatic localization systems that the direct paths between an unknown position transmitter and the receivers are absent or blocked. Moreover, the receivers may not be able to time-synchronize with one another. To enable the effective localization of a moving object, we introduce calibration objec...

In modern radar and Integrated Sensing and Communication (ISAC) systems, the conventional point-scatterer assumption becomes increasingly inaccurate due to higher spatial resolution. In this context, Extended Target Tracking (ETT) has grown interest in recent years. However, most existing ETT works are designed for mon...

Multistatic ranging with mobile receivers enables good tracking performance due to the combined adaptive sensor geometry. However, environments that contain signal obstructing obstacles require receiver trajectory planning to maintain line-of-sight (LOS) conditions with transmitters and the target of interest. In this...
