Abstract
This paper proposes a low-complexity localization framework for moving targets using a single-antenna mobile radar platform with orthogonal time-frequency space (OTFS) waveforms. Unlike conventional approaches requiring antenna arrays or multistatic configurations, the proposed method exploits synthetic aperture (SA) motion to estimate target positions from estimated delay-Doppler (DD) parameters. An efficient DD tracking algorithm is introduced to incrementally update delay and Doppler estimates across OTFS blocks, avoiding full re-estimation and reducing computational overhead. Then, a geometry-based localization strategy reconstructs the target coordinates from the quadratic curvature of the slant-range trajectory during the aperture-synthesizing period. Simulation results demonstrate the impacts of the synthesis aperture, platform and target velocities on the achievable localization accuracy.
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 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...

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...

In long-aperture forward-looking radar, nonlinear Doppler mismatch caused by target relative motion can lead to positioning deviation and image defocusing. To address this issue, an adaptive segmented Doppler compensation method based on phase error constraints is proposed. As synthetic aperture time increases, high-or...

Localizing an autonomous underwater vehicle without pre-deployed seabed transponders, or direct access to onboard vehicle sensors remains a core challenge. We present a receiver-passive 3-D localization and spatial mapping system utilizing a single floating surface buoy equipped with a hydrophone array and an inertial...

For effective imaging, detection, and tracking with terahertz video synthetic aperture radar (THz-ViSAR), the precise parameter estimation of ground moving targets (GMTs) serves as an essential prerequisite. To obtain precise motion parameters, this article proposes a shadow-based estimation method for estimating GMT p...
