The unique, bi-pedal motion of humans has been shown to generate a characteristic micro-Doppler signature in the time-frequency domain that can be used to discriminate humans from not just other targets, but also between different activities, such as walking and running. However, the classification performance increasingly drops as the aspect angle between the target and radar approaches perpendicular, and the radial velocity component seen by the radar is minimized. In this paper, exploitation of the multi-static micro-Doppler signature formed from multi-angle observations of a radar network is proposed to improve oblique-angle classification performance. The concept of mutual information is applied to find the order of importance of features for a given classification problem, thereby enabling the selection of optimal features prior to classification. Strategies for fusing multistatic data using mutual information and model-based approaches are discussed.

Mutual Information of Features Extracted from Human Micro-Doppler
Tekeli, Burkan; Gurbuz, Sevgi Zubeyde; Yüksel Turgut, Ayşe Melda (2013-01-01)
The unique, bi-pedal motion of humans has been shown to generate a characteristic micro-Doppler signature in the time-frequency domain that can be used to discriminate humans from not just other targets, but also between different activities, such as walking and running. In the literature, many different features have been proposed for classification applications. However, it is not known which features have a greater impact on classification performance, or indeed how many features should be used to achiev...
Analysis and Control of a Dissipative Spring-Mass Hopper with Torque Actuation
Ankaralı, Mustafa Mert; Saranlı, Uluç (2011-01-01)
It has long been established that simple spring-mass models can accurately represent the dynamics of legged locomotion. Existing work in this domain, however, almost exclusively focuses on the idealized Spring-Loaded Inverted Pendulum (SLIP) model and neglects passive dissipative effects unavoidable in any physical robot or animal. In this paper, we extend on a recently proposed analytic approximation to the stance trajectories of a dissipative SLIP model to analyze stability properties of a planar hopper w...
Stability and control of planar compass gait walking with series-elastic ankle actuation
KERIMOGLU, Deniz; MORGUL, Omer; Saranlı, Uluç (2017-03-01)
Passive dynamic walking models are capable of capturing basic properties of walking behaviours and can generate stable human-like walking without any actuation on inclined surfaces. The passive compass gait model is among the simplest of such models, consisting of a planar point mass and two stick legs. A number of different actuation methods have been proposed both for this model and its more complex extensions to eliminate the need for a sloped ground, balancing collision losses using gravitational potent...
ACOUSTIC SURFACE PERCEPTION FOR IMPROVED MOBILITY OF LEGGED ROBOTS
Ozkul, Mine Cuneyitoglu; Saranlı, Afşar; Yazıcıoğlu, Yiğit (2012-08-15)
A dynamically dexterous legged robot has the distinct property that the legs are continuously interacting with the environment. During walking and running, this interaction generates acoustic signals that carry considerable information about the surface being traversed, state of the robot legs and joint motors as well as the stability of the locomotion. Extracting a particular piece of information from this convolved acoustic signal however is an interesting and challenging area of research which we believe...
Synchronization of multiple serially actuated robotic legs using virtual damping control
Özen, Merve; Saranlı, Uluç; Department of Computer Engineering (2018)
Even though one-legged models have been found to be a useful fundamental basis for understanding and controlling the dynamics of running, animals and physical robots alike often use multiple legs for additional support, dexterity, and stability. In general, the dynamics of such multi-legged morphologies are more complex and their control is more difficult. A common problem in this context is to achieve a particular phase relationship between periodic oscillations of different legs, resulting in different lo...
