Unlike the design of Strategic Radars, which detects point targets, the design of Atmospheric Radars is very complex. These Radars deal with distributed targets with minimal back scattering (RCS). A VHF Mesosphere Stratosphere Troposphere (MST) Radar, having very high power aperture product (Figure of Merit) was designed, developed, installed and commissioned indigenously for ISRO/DOS, which is being operated over last 30 years. Design/developmental details of this Radar will be discussed in the interactive lecture. Co-sponsored by: IEEE AP-MTTS SBC IIT Kharagpur Speaker(s): K. P.

A survey of some of the recent advances in the field of microwave and millimeter-wave imaging is presented. This technology originally evolved from the approaches used in radar, and has been an active area of research since then, the primary attraction being the possibility of “seeing” objects hidden behind some opaque material such as wood, paper, concrete, fog etc. It is well-known that microwave/mm-wave signals ( usually defined as 0.3 – 300 GHz ) can penetrate such materials to greater or smaller depths depending on frequency , as opposed to visible light or infra-red whose penetration in most cases is negligible. The applications are well-known today and many systems are in everyday use such as security screening , medical imaging , through the wall imaging for surveillance, non-destructive testing etc. Usually imaging systems operate in the “near field” in the sense that the distance to the target is of the same order as the size of the complete sensor set – most imagers use multiple antennas for receiving the microwave signal from the target and the sensors are physically spaced out in a region usually much larger than wavelength. In contrast there are a few imagers which operate in the radar mode where the object is located in the far-field of the antenna array. In this talk we will describe some of the recent systems which have been developed by different researchers and which are likely to form the basis of future imagers used commercially , including for security applications.

Understanding the connection between the brain’s structural connectivity and its functional connectivity is of immense interest in computational neuroscience. Some studies have suggested that whole brain functional connectivity is shaped by the underlying structure, the rule by which anatomy constraints brain dynamics remains an open question. In this talk, I will discuss a computational framework that identifies a joint subspace of eigenmodes for both functional and structural connectomes. We further learned the joint eigen spectra of both the connectomes in order to predict the functional connectome of a subject from the structural counterpart. In the second part of the presentation, I will discuss a deep learning framework for classification of tinnitus disease, which is an auditory phantom perceptual disorder. Motivated by the evidence of subtle anatomical or functional morphological information in magnetic resonance images (MRI) of the brain, we developed a data-driven framework for tinnitus classification (tinnitus or healthy subject) and prediction of tinnitus severity. The proposed classification method could be used for early detection, monitoring clinical trials, and tracking the progression of the disease.

Ultrasound is rapidly evolving and can now provide information about tissue structure and stiffness for enabling objective diagnosis. Hermite-scan (H-scan) imaging is a new approach for characterizing tissue structures based on color-mapping of scatterer sizes. In H-scan imaging, radiofrequency (RF) echoes are matched to Gaussian-weighted Hermite polynomials of order n, which are related to the size of scatterers. Furthermore, shear wave viscoelastography exploits the shear wave generated by an ultrasound beam and extracts the viscoelastic properties of tissues from the frequency dependence of the measured wave velocity. In this talk, I will demonstrate the feasibility of differentiating glioblastoma tumors from normal brain tissue ex vivo using H-scan imaging, with potential applications in intraoperative brain tumor imaging. I will also discuss our work on validating shear wave viscoelastography on viscoelastic tissue-mimicking phantoms.
