    Harmonic radar technology has been researched and developed for studying the foraging behaviour of insects such as honey bees in order to study their decline in the ecosystem. The traditional radar fails to detect the bees ...
  • Estimating radar detection coverage probability of targets in a cluttered environment using stochastic geometry 
    Singh, Gaurav; Ram, Shobha Sundar (Advisor) (IIIT-Delhi, 2020-07)
    We analyze the performance of a radar in an environment where clutter is constituted by discrete scatterers whose radar cross-sections are comparable to that of the target. An indoor radar deployment to detect humans in ...
  • High-resolution digital frequency synthesizer for 77 ghz automotive radar transmitters 
    Pandey, Veeraj; Ram, Shobha Sundar (Advisor); Bal, Ankur (Advisor) (IIIT-Delhi, 2020-06)
    A high resolution 77GHz linear chirp signal synthesizer for a monostatic frequency modulated continuous wave (FMCW) radar is presented. The proposed linear frequency modulation design uses a fixed frequency multi-stage ...
  • Imaging using radar 
    Iqbal, Mohd Shoaib; Ram, Shobha Sundar (Advisor) (IIIT-Delhi, 2017-11-25)
    Frontal radar imaging has been proposed as an alternate technology to cameras for through wall surveillance and law enforcement. Cameras cannot see through wall as optic frequencies do not penetrate walls. On the other ...
  • Learning algorithms for micro-doppler radar based detection, classification and imaging of humans in indoor environments 
    Vishwakarma, Shelly; Ram, Shobha Sundar (Advisor) (IIIT-Delhi, 2020-02)
    Indoor radars have been researched and developed to detect and monitor humans for applications that range from law enforcement, security and surveillance purposes to ubiquitous sensing applications such as smart home or ...
  • Leveraging EMI signals for appliance detection and energy harvesting 
    Gulati, Manoj; Ram, Shobha Sundar (Advisor); Singh, Amarjeet (Advisor) (IIIT-Delhi, 2020)
    Electromagnetic interference (also known as EMI) is a byproduct of high-speed switching circuits used inside most of present-day electrical and electronic appliances. EMI propagates through conduction along the power lines ...
  • Probability of target detection in bistatic and multistatic radars 
    Singhal, Shubhi; Ram, Shobha Sundar (Advisor) (IIIT-Delhi, 2022-05)
    In the first part of the work, we evaluate the detection performance of a bistatic radar using a metric called bistatic radar detection coverage probability. The setting considered for the target detection consists of noise ...
  • Radar sensor networks 
    Badri, M.; Raman, Rajiv (Advisor); Ram, Shobha Sundar (Advisor) (IIIT- Delhi, 2021-05)
    This work aims at interference mitigation in recently booming automotive radar networks, via careful beam forming techniques based on Geometric Algorithms and Optimizations. We first thoroughly explore a relatively simple ...
  • Reduced mutual coupling for through wall radars using orthogonally polarized antennas 
    Kaur, Guntaas; Ram, Shobha Sundar (Advisor) (IIIT-Delhi, 2017-12)
    There has been a growing interest in building through-the-wall radars (TWR) for law enforcement, security and biomedical applications for tracking humans in urban environments. Designing the antennas for such systems is a ...
  • Software and hardware prototype of ieee 802.11ad based joint radar communication transmitter 
    Jain, Soumya; Ram, Shobha Sundar (Advisor); Darak, Sumit Jagdish (Advisor) (IIIT-Delhi, 2022-07)
    Next-generation wireless communication systems are expected to support high-mobility and high-bandwidth vehicle-to-everything (V2X) communications in sub-6 GHz and millimeter wave (mmWave) spectrum. The deployment in mmWave ...
  • Software prototype of IEEE 802.11ad based joint radar communication receiver 
    Sindhu, V Sri; Ram, Shobha Sundar (Advisor); Darak, Sumit Jagdish (Advisor) (IIIT-Delhi, 2022-09)
    Rapid beam alignment is required to support high gain millimeter wave (mmW) communication links between a base station (BS) and mobile users (MU). The standard IEEE 802.11ad protocol enables beam alignment at the BS ...
  • Solving helmholtz equation with compressed sensing enhanced finite element methods 
    Sharma, Pragya; Ram, Shobha Sundar (Advisor) (2015-12-07)
    The generalized finite element method (FEM) approach towards solving the Helmholtz equation involves a very high computational complexity of the order of O(n3) where n is the number of nodes of the FEM formulation. Prior ...
  • Two dimensional metamaterial slot antenna for improved directivity 
    Jain, Rohit; Ram, Shobha Sundar (Advisor) (2014-07-10)
    Directivity of an antenna is a figure of merit which shows how effective an antenna is at transmitting / receiving in a desired direction. A highly directive antenna is useful for applications such as satellite communications ...
