This study aims to experimentally investigate the feasibility of discriminating human motions with the help of micro Doppler features by using radar. In the first phase of the work, the synthetic data is generated through the human walking simulator by V. Chen and different time-frequency transformations are applied on the data and the results of the simulator are compared with field experiments. In the following phase, several field experiments which are in the scope of the simulator are conducted and the experimental data for running, crawling, creeping and walking with the aspect angles of 0 degrees, 30 degrees, 60 degrees are collected. Signal processing steps and micro Doppler processing steps are applied to the collected data and spectrograms are obtained. Lastly, six features, which are torso frequency, bandwidth of the signal, offset of the signal, bandwidth without micro Dopplers, the standard deviation of the signal strength, the period of the arms or legs motions are extracted from the spectrograms and the efficiency of the features in motion classification is compared.

The Application of micro doppler features in target classification
Topuz Alemdaroğlu, Özge; Yıldırım, Nevzat; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2014)
This study aims to experimentally investigate the feasibility of discriminating human motions with the help of micro Doppler features by using radar. In this work, the human walking simulator by V. Chen is examined and is modified according to requirements of the study. Then, the time-frequency distributions to obtain the spectrograms of human motions are examined and the Wigner Ville Distribution and Short Time Fourier Transform (STFT) are chosen for the application. After the simulation studies, experimen...
A generative model for multi class object recognition and detection
Ulusoy, İlkay (2006-01-01)
In this study, a generative type probabilistic model is proposed for object recognition. This model is trained by weakly labelled images and performs classification and detection at the same time. When test on highly challenging data sets, the model performs good for both tasks (classification and detection).
The role of synchronization of neural structures on neuron dynamics Nöral yapilarda senkronizasyonun hücre dinamikleri üzerine etkisi
Karabacak, Ozkan; Elibol, Rahmi; Şengör, Neslihan Serap (2014-01-01)
Due to the measurement techniques developed, it is now possible to observe signals at different levels in neural structures. These observations give rise to increasing works dealing with setting up the relation between such signals and cognitive processes, neurodegenerative diseases and neurobehavioral disorders. Computational neuroscience is becoming more influential in investigating the mechanisms underlining these signals. Especially oscillations in different neural structures and the role of these oscil...
An Improved Receiver for Harmonic Motion Microwave Doppler Imaging
Soydan, Damla Alptekin; Irgin, Umit; Top, Can Baris; Gençer, Nevzat Güneri (2020-03-01)
© 2020 EurAAP.Harmonic motion microwave Doppler imaging is a novel imaging modality that combines focused ultrasound and radar techniques to obtain data based on mechanical and electrical properties of the tissue. In previous experimental studies, the Doppler component of the scattered signal is sensed and used to create 2D images of a tumor inside a homogeneous fat phantom. Due to the drawbacks of the receiver configuration, scanning time was high, the signal-to-noise ratio was low, and the multi-frequency...
