Joint Weak Signal Detection and Carrier Frequency Offset Estimation for Communication in Multistatic Collaborative Passive Radar

IET Communications, Volume 19, Issue 1, January/December 2025.
A virtual array‐based method is proposed to jointly detect communication signals and estimate the starting position and cCFO. It constructs virtual arrays based on the linear phase characteristics of the training sequence regardless of the specific signal structure, which allows it a wide range of applications.

An ISAR target motion estimation algorithm based on a differential semblance criterion

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This study presents a novel approach for improving rotational motion estimation in multistatic Inverse Synthetic Aperture Radar (ISAR) imaging through a Differential Semblance Optimization (DSO) criterion. By reducing discrepancies across images from multiple transmitter–receiver pairs, our method enables precise yaw rotation estimation and produces ...

A Phase Synchronization Method for Miniature Multistatic FMCW SAR

Leida xuebao
The miniature multistatic Synthetic Aperture Radar (SAR) system uses a flexible configuration of transceiver division compared with the miniature monostatic SAR system, thereby affording the advantages of multi-angle imaging. As the transceiver-separated

3-D Moving Target Localization in Multistatic HFSWR: Efficient Algorithm and Performance Analysis

Remote Sensing
High-frequency surface wave radar (HFSWR) is unable to measure the target’s altitude information due to its limited antenna aperture in the elevation dimension.

Multistatic Passive Detection of Cyclostationary Signals

ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
In this work we consider a multistatic passive detection problem, which is motivated by a multiple-input multiple-output (MIMO) passive radar application. Specifically, we consider a single illuminator of opportunity (IO) and several surveillance and reference arrays for the detection of a Gaussian cyclostationary signal in temporally colored and ...
