On the anti‐intercept features of noise radars

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1014-1035, July 2024.
An evaluation of the related Low Probability of Detection, of Intercept and of Exploitation is presented for Continuous‐Emission Noise Radar waveforms with different operational parameters, that is, “tailored”, and with various “degrees of randomness”. The effect of “tailoring” is analysed with prospects for future work.

MMW‐FC: A novel railway fastener detecting method based on millimetre wave radar for train positioning

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1094-1105, July 2024.
A novel method is proposed for rail fastener detection based on millimetre‐wave radar, which can accurately detect and enumerate the fasteners in real‐time as the train traverses its route. Under circumstances where GNSS signals remain unavailable for prolonged durations, precise train localisation can be accomplished by correlating the number of ...

Radar Micro‐Doppler Signature Generation Based on Time‐Domain Digital Coding Metasurface

Advanced Science, Volume 11, Issue 19, May 22, 2024.
A low‐cost and high‐flexible radar micro‐Doppler signature generation platform is proposed based on metasurface. The presented metasurface contains time‐varying modulation periods, thus capable of supplying the electromagnetic signals with designable micro‐Doppler frequencies to describe micro‐motions of different objects.

A design of a high‐resolution frequency modulated continuous wave radar for drone detection based on spurious phase noise and discrete clutter reduction

IET Radar, Sonar &Navigation, Volume 18, Issue 5, Page 704-714, May 2024.
A new approach with detailed descriptions from both theoretical and practical points of view is introduced for radar drone detection based on discrete clutter reduction and phase noise mitigation. Abstract The authors deal with the problem of the design and manufacture of a high‐resolution FMCW radar for drone detection and classification.

Compact 340 GHz homodyne transceiver modules for FMWC imaging radar arrays. [PDF]

, 2016
We present a solution where one single LO chain is used to feed a homodyne FMCW radar transceiver. An InGaAs pHEMT active frequency multiplier MMIC (x8) and a Schottky diode frequency doubler make up the LO chain.

Accurate Radar-Based Heartbeat Measurement Using Higher Harmonic Components

IEEE Access
This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, in combination with the variational mode extraction method, which is a type of mode ...
