An X-Band Monopulse Direction-Finding Receiver Based on a Rat-Race Comparator and a Antipodal Vivaldi Array
M. Ahmad Nabil, Sohaib Yaqoob Chaudhry, Salman Liaquat
This paper presents the design, fabrication, and experimental validation of a compact monopulse direction-finding (DF) receiver operating in the X-band. The receiver combines a $2…
Design and Experimental Validation of a Multiband Cross-Polarization Conversion (CPC) Metasurface for Radar Cross Section (RCS) Reduction
Sohaib Yaqoob Chaudhry, Malik Muhammad Abdullah, Salman Liaquat +3
Radar cross-section (RCS) reduction is a fundamental requirement in modern stealth technology, playing a critical role in the low-observable performance of aerial and naval platfor…
A Closed-Form Noise-Sensitivity Asymmetry for Causal Branch Selection in Minimal-Array TDoA Localization
Abeer Nasir Chaudhry, Salman Liaquat, Hasan Saeed Mir
Minimal-array time-difference-of-arrival (TDoA) localization with three planar receivers reduces to a scalar quadratic whose two roots can both be feasible target positions, leavin…
: A Geometry-Quality Metric Complementary to GDoP for Closed-Form TDoA Multilateration
Abeer Nasir Chaudhry, Salman Liaquat, Muhammad Mohsin Khadim
The Geometric Dilution of Precision (GDoP) characterizes the noise sensitivity of a Time-Difference-of-Arrival (TDoA) localization system, but does not capture every way the analyt…
Feature-Level Robustness of Physics-Guided Micro-Doppler Descriptors for classification of Drones and Birds
Shaiq e Mustafa, Salman Liaquat, Imran Hafeez Abbasi +1
Micro-Doppler signatures are a proven modality for discriminating between drones and birds, but their reliability degrades in low-SNR, data-constrained settings where deep learning…
Using Continual Learning for Real-Time Detection of Vulnerable Road Users in Complex Traffic Scenarios
Faryal Aurooj Nasir, Salman Liaquat, Nor Muzlifah Mahyuddin
Pedestrians and bicyclists are among the vulnerable road users (VRUs) that are inherently exposed to intricate traffic scenarios, which puts them at increased risk of sustaining in…
Dual RIS-Assisted Monostatic L-Band Radar Target Detection in NLoS Scenarios
Salman Liaquat, Ijaz Haider Naqvi, Nor Muzlifah Mahyuddin
The use of a single Reconfigurable Intelligent Surface (RIS) to boost the signal-to-noise ratio (SNR) at the radar offers significant improvement in detecting targets, especially i…
SDR-Based Metal Classification using Spectrogram Images from Micro-Doppler Signatures
Salman Liaquat, Faran Awais Butt, Faryal Aurooj Nasir +4
Metallic materials such as brass, copper, and aluminum are used in numerous applications, including industrial manufacturing. The vibration characteristics of these objects are uni…
