Antenna measurement facility
The NFTR system is a planar near field antenna test system. It is capable of testing the Near field (NF) and Far field (FF) characteristics of the Active & Passive Antenna/Array under test. The features of the constituents of the NFTR are:
Shielded Anechoic Chamber
The Shielded Chamber is lined with the Radiation Absorbing material and houses scanner, optical subsystem, Probe and AUT. The platform is specially designed for high isolation to vibration. The chamber with large volume of 17mx15mx11m can accommodate large size radar systems. The temperature and humidity inside, is controlled by a dedicated air-conditioning system.
Scanner
Scanner is a high precision robotic system carrying sensors used to measure the Electrical and mechanical performance of microwave antennas. It comprises three orthogonal linear motion axes (X-Y-Z). X,Y for moving the probe across the scan plane and Z for adjusting the separation between the scan plane and the AUT. In addition, one rotary axis (Roll) is provided for rotating the probe about its axis in order to enable probing different polarization components of the planar NF. The scan range is 12m x 7m x 1m.
RF & Computational Subsystem
The RF measurement subsystem is based on a Vector Network Analyser operating up to 18GHz. It consists of a RF signal source section as the stimulus source and an amplitude/phase measurement receiver section for the response measurement. The measurement can be made in Transmit, Receive and Inject mode using the RF switch.
The computational subsystem controls the scanner, RF subsystem, Laser subsystem and acquires the data from the probe and analyses the near field and far field characteristics. The system operates on the state of the art MIDAS software and utilizes Fast Fourier Transform techniques for data conversion from NF to FF.

(Independent Director)
I have 38 years of experience in governance and have held senior positions in decision making capacities in practically all sectors – the developmental, agricultural, social, industrial, infrastructural, transportation, economic and regulatory. I joined Government in 1975, after standing first in the combined merit list for IFS/IAS, and opting to serve in the IAS.
I have worked with distinction in areas as diverse in their geography and the nature of their problems as the National Capital Territory of Delhi, Goa, the Andaman and Nicobar Islands, and Arunachal Pradesh. About half my career has been in Government of India, in the Ministries of Human Resource Development, Housing and Urban Poverty Alleviation, Textiles and Shipping, where I have been instrumental in shaping policy for elementary education and growth of textiles in a globally competitive market; preparing programmes for slum housing; crafting regulation for cleaner air in Delhi by the introduction of CNG buses and four stroke autorickshaws; and designing stimulation packages for the housing construction and textile industries in the two-humped economic downturn since 2008. My longest stints have been in Education and Textiles; I have left a mark also in the shipping sector and the Delhi transport department. I retired in the rank of Secretary to Government of India, in 2013, after being one of the lon gest serving secretaries to government with almost five years of service in that rank. Post retirement, I was appointed as Chairperson, Board of Governors of the National Institute of Fashion Technology (NIFT), a deemed university set up under an Act of Parliament, for a three year tenure, from 1-04-2013 to 3103-2016.
I have had several years of corporate experience during my career, having served as Government Director or Chairman on the Board of several CPSUs, or supervised their functioning. These included the Delhi Tourism and Transport Development Corporation,the Delhi Metro, the National Housing Bank, the Housing and Urban Development Corporation, the Cotton Corporation of India, the Central Cottage Industries Corporation, etc.
