Technology Focus Areas at CAIR
CAIR’s product development efforts are based on continued nurturing of core competence in relevant technology areas.
Net Centric Systems for Tactical Command Control & Communication Systems
Command Control Communication and Intelligence (C3I) System consisting of networked computers in the tactical battle area facilitates comprehensive situation awareness by the commanders for timely and optimum decision-making.
CAIR has developed a series of C3I systems for the different branches of Indian Army. The specific technical domains that have contributed to this effort are:
Communication and Networking
CAIR is engaged in developing technologies needed for futuristic tactical communication network for the Indian Army. The lab is assisting the user in specifying the system architecture and the subsystem specifications for their futuristic Tactical Communication System (TCS). Preliminary R&D activity has been launched in anticipation of the Government of India sanction of a major program for the development of TCS.
Geographical Information System (GIS)
INDIGIS is an indigenously developed geographical Information system for military applications. INDIGIS helps in visualization, analysis and measurements of spatial objects such as digital vector maps, satellite images, digital elevation models and bathymetric data in the form of electronic navigation charts.
Signal processing is an important activity at CAIR, with emphasis on speech signal processing. In the area of speech coding, a Linear Predictive Coder (LPC) based voice coder that encodes 4 kHz band limited telephone quality analogue speech into a 2.4 kbps digital stream has been developed. In the area of Automatic speech processing, solutions for speaker independent speech recognition and language independent speaker identification have been developed and continue to be active areas of work.
R&D efforts at CAIR are directed towards realization of feasible, reliable, secure MANETs and WSNs. Many of the challenges have been successfully addressed by scientists working on the associated projects.
Intelligent Systems and Unmanned Systems
CAIR is working in the field of Intelligent Unmanned Systems, Computer Vision Processing and Artificial Intelligence.CAIR has developed various multipurpose robots including industrial grade capability robots and futuristic research oriented robotic platforms. CAIR has been involved in the research and development activities inthe area of computer vision.A comprehensive library for image and video processing techniques has been developed. An image map display system has been developed to overlay images on maps at various resolutions. CAIR is focused towards establishing Artificial Intelligence (AI) technologies which can be applied for the rich problem areas in the military domain. Towards this end, CAIR has established a comprehensive data-mining toolbox, with a large number of data mining algorithms, which can be used in different problem spaces.
CAIR has established a decision support system (DSS) framework, which is completely driven by knowledge base maintained as ontologies. Algorithms like Multi Criteria Decision Making (MCDM), Swarm Algorithms, Game theoretic approaches towards resource allocation, Search algorithms etc. built on the distributed framework of Hadoop, support in giving “intelligent” and informed solutions. This framework has been used for providing Decision Support for Deployment, Transport Allocation, Convoy composition and scheduling and Coastal Surveillance.
To provide for a completely decoupled distributed solution, CAIR is working towards a semantically enabled service oriented architectural framework. CAIR has also made significant effort in establishing AI algorithms for path planning, Simultaneous localization and mapping (SLAM), Object detection and recognition, and task coordination for mobile platforms.
CAIR has been involved in the development of technologies for realizing industrial and mobile robots. Dedicated technologies have to be established to address the unique constraints imposed by the two types of robotics systems. Accordingly, specific endeavor meets this requirement.
CAIR has developed a wide range of communication security systems for securing speech, fax or data that can be transmitted over leased lines, telephone lines, IP Networks, radio links, satellite terminals, frame relay networks, fiber optic networks supporting a wide bit rate of operations from few Kbps up to Gigabits/sec etc. These systems are built on custom hardware platforms encrypting at wire-line speed with minimal latency and overheads.
Information security aims at securing confidentiality and integrity of the data stored in computers and communicated over networks. CAIR has been working on the following areas in this field:
Secure Communication, Authentication (including speech biometrics), Network access control, Traffic analysis and network Intrusion Detection Systems (IDS).
CAIR has brought out a number of specific products/ solutions in the above areas and has successfully delivered to the different user communities. These include High speed traffic analysis software, Secure e-mail, Information security gateway, IP security, Network and Host Intrusion Detection Systems, On-line disk encryption (Secure Storage), Smart card based authentication, Multi-layer network Firewall, Personal (host) firewall, etc.
