Generalized Cramer-Rao Bound for Joint Estimation of Target Position and Velocity for Active and Passive Radar Networks

In this paper, we derive the Cramer-Rao bound (CRB) for joint target position and velocity estimation using an active or passive distributed radar network under more general, and practically occurring, conditions than assumed in previous work. In particular, the presented results allow nonorthogonal signals, spatially dependent Gaussian reflection coefficients, and spatially dependent Gaussian ...

Joint relative position and velocity estimation for an anchorless network of mobile nodes

Localization is a fundamental challenge for any network of nodes, in particular when the nodes are in motion and no reference nodes are available. Traditionally, the Multidimensional scaling (MDS) algorithm is employed at discrete time instances using pairwise distance measurements to find the relative node positions (with arbitrary rotation). In this paper, we present a novel framework to loca...

Joint Polarization and Angle Estimation for Robust Multi-Target Localization in Bistatic MIMO Radar

In the paper, we propose a novel algorithm using joint polarization and angle information for robust and high-resolution multi-target localization in bistatic multipleinput multiple-output (MIMO) radar system. The proposed algorithm exploits the singular value decomposition (SVD) of cross-correlation matrix of the received data from two transmitter subarrays to obtain robust performance in nois...

Joint use of Σ and Δ channels for multiple radar target DOA estimation

This work deals with the problem of estimating the directions of arrival (DOA) of multiple radar targets present in the same range-azimuth resolution cell of a surveillance radar by joint processing the sum (Σ ) and delta ( ∆ ) channel data. The AMLRELAX estimator, previously derived by the authors, is extended to a two-channel system, and compared to the classical monopulse system.
