Micro-doppler classification of humans and animals using FMCW radar
… animal target classification by making use of micro-Doppler data generated by a Frequency-Modulated Continuous Wave (FMCW) radar. Raw Analogue to Digital Converter (ADC) data was collected of human and animal species including dogs, horses and cows. Signal processing techniques such as creating …

PULSED RADAR TARGET RECOGNITION BASED ON MICRO-DOPPLER SIGNATURES USING WAVELET ANALYSIS
… Such an echo signal contains the target's micro-Doppler (μ-D) signature as well as its macro-motion related parameters. This thesis presents and compares three different approaches to develop such a system to distinguish between humans, dogs and background clutter using a low power pulsed …

Remote Vibration Estimation Using Displaced Phase Center Antenna SAR in a Strong Clutter Environment
… on the returned radar signal termed the micro-Doppler e\ufb00ect. The ability to estimate the targets vibration frequency and vibration amplitude by exploiting the micro-Doppler e\ufb00ect, all while in a high clutter environment can provide strategic information for target …

Helicopter blade parameter extraction for purposes of radar target indentification
… on an airborne target cause additional Doppler modulation in the return signal, known as the micro-Doppler effect. Information on the rotating structures can be extracted from this effect. A technique based on time- frequency and tomographic analysis is introduced in this research to …

Radar Detection, Tracking and Identification for UAV Sense and Avoid Applications
… prototyping of novel radar techniques such as micro-Doppler radar target identification or cognitive radar. To enable empirical radar signal processing evaluations, an S-Band and X-Band frequency modulated, software-defined radar testbed is designed, implemented, and evaluated with field …

Radar-based Environment Perception for Pre-Crash Safety Systems
… radar data. The technique spatially resolves the micro-Doppler signals, generated by the rotating wheels of the target vehicle, to determine characteristic scatter points on the target surface. A micro-Doppler parameter is defined to quantify detections that are with high probability generated by …

Advanced signal processing solutions for ATR and spectrum sharing in distributed radar systems
… of a simple fusion rule.A model-based micro-Doppler algorithm is developed for the identification of helicopters. The approach relies on the proposed sparse representation of the signal scattered from the helicopter’s rotor and received bythe radar. Such a sparse representation is …

Advancements in Satellite SAR Methods for Monitoring Civil Infrastructure
… for measuring long-term displacement and micro-Doppler SAR (MDSAR) for measuring structural vibrations. The first part of the thesis discusses the issues of conventional InSAR for bridge applications, including phase ambiguity and the use of deformation models that do not accurately …
