Detection of specular targets is a significant challenge for single-platform radar systems. The mirror-like reflections direct energy away from the radar receiver, reducing the signal-to-noise ratio (...
Static radar parameters fix the obtainable sensing range and force high RF power/gain, often wasting energy and requiring multiple modules to cover different ranges. We develop a closed-loop, range-aw...
This paper presents a state-of-the-art FMCW imaging radar system capable of both high resolution diffraction-limited 3-D imaging and micro-Doppler based speech reconstruction. The system consists of a...
This paper presents a low-loss, wideband dielectric resonator antenna (DRA) integrated on a system-in-package (SiP) for high-performance 60 GHz radar modules. Conventional patch-based radars suffer fr...
A fully integrated 18.6–20.4 GHz FMCW synthesizer for automotive radar applications is presented. The design employs a dual-loop PLL with feedback down-conversion and a transformer-based VCO to addres...
This paper proposes an active calibration method for millimeter-wave beamforming arrays by estimating elements' excitations under realistic operating conditions. The method leverages far-field tr...
This paper presents a novel measurement approach for characterizing the error vector magnitude (EVM) of a transmitter using a reverberation chamber (RC). The method is demonstrated by measuring a powe...
In modern radar applications, signals are becoming more and more complex. In addition to frequency hopping, the pulses are modulated to enable pulse compression techniques and increase the range resol...
Traditional microwave filter design typically relies on iterative parameter tuning and predefined topologies, which limits design space and increases development time. This study uses a deep learning ...
Satellite networks play a crucial role across various domains, including Global communication — Delivering connectivity in remote and rural areas lacking terrestrial infrastructure, Navigation &am...
