Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the range gate .
In telecommunications and radar engineering, the antenna boresight is the axis of maximum gain (maximum radiated power) of a directional antenna.For most antennas the boresight is the axis of symmetry of the antenna.
Consider a radar with a constant interval between pulses; target reflections appear at a relatively constant range related to the flight-time of the pulse. In today's very crowded radio spectrum, there may be many other pulses detected by the receiver, either directly from the transmitter or as reflections from elsewhere.
Jawaharlal Nehru Technological University Kakinada (JNTU Kakinada) is a public university in Kakinada of Andhra Pradesh, India. It is one of India's universities focusing on engineering. The university has been accredited by the National Assessment and Accreditation Council (NAAC) of the University Grants Commission (UGC) with an "A+" grade.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

The world's first airborne monopulse radar system was the British Ferranti-designed AIRPASS system which went into service in 1960 on the RAF's English Electric Lightning interceptor aircraft. An early monopulse radar development, in 1958, was the AN/FPS-16, on which NRL and RCA collaborated. The earliest version, XN-1, utilised a metal plate lens.
Jawaharlal Nehru Technological University, Hyderabad (JNTU Hyderabad) is a public university, located in Hyderabad, Telangana. Founded in 1965 as the Nagarjuna Sagar Engineering College , it was established as a university in 1972 by The Jawaharlal Nehru Technological University Act, 1972 .
