Multistatic Modular Real‐Time MIMO‐SONAR Systems

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Multistatic SONAR networks (MSNs) improve underwater imaging quality due to increased degrees of freedom. Techniques for bistatic processing, elliptical interpolation and data merging are described, and a real‐time modular SONAR imaging system equipped with these algorithms is tested. Simulations and real‐world measurements demonstrate the capabilities

Tensor Formulation of Kalman Filter and Linear Quadratic Gaussian Controller for Applications on Multilinear Dynamical Systems

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
A generalisation of the Kalman Filter and Linar Quadratic Gaussian controller to deal with multi‐sensor and multi‐agent/target scenarios is developed through tensor algebra. Applications of the tensor‐LQG allow developing parallel optimal control and waveform design suitable for multi‐radar and multi‐agent/target systems.

Performance analysis of ground‐based long baseline radar distributed systems for space situational awareness

IET Radar, Sonar & Navigation
Detection of space objects is a key component of space situational awareness, which could help prevent and minimise space collisions. While there have been lots of radar systems designed to detect space objects, few of them have dealt with long baseline ...

A Computationally Economic Location Algorithm for Bistatic EVMS-MIMO Radar

IEEE Access, 2019
In this paper, we investigated into the problem of target location in a bistatic multiple-input multiple-output (MIMO), whose transmit antennas and receive antennas are electromagnetic vector sensors (EMVS).

Efficient Multiplatform Motion Error Calibration Using Strong Scatterers With Position Uncertainty in Asynchronous Airborne Distributed Radars

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This work addresses the problem of multiplatform motion error calibration (multiplatform position and velocity errors) in an asynchronous airborne distributed radar network with the employment of ground strong scatterers (SSs) at inaccurate locations.

A Low‐Cost FMCW Radar for Perimeter Surveillance With Suppression of Impact of Trees and Bushes as Clutter

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
This paper presents the design and implementation of a low‐cost frequency modulated continuous wave radar system in the X‐band for perimeter surveillance applications. To address the challenge of differentiating pedestrians from clutter caused by trees and bushes, the radar uses a simple method with two receiving antennas and one transmitting antenna ...
