Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Since a DRFM system is designed to create a false target to a radar system, this technology can be employed to perform hardware-in-the-loop simulation. [1] [2] Hardware-in-the-loop simulation is an aid to the development of new radar systems, which allows for testing and evaluation of the radar system earlier in the design cycle. This type of ...
The 1st year exam of +2 is conducted in college level.for 2nd year +2 the final exam is conducted by CHSE.And two more exam of 2nd year i.e. test exam and pretest exam is conducted by college authority. The +2 exam is of total 600 marks practical paper are distributed in 70(theory)+30(practical).& language paper is of 100 mark.
Further examination of the basic Radar Spectrum shown above shows that the information in the various lobes of the Coarse Spectrum is identical to that contained in the main lobe, so limiting the transmit and receive bandwidth to that extent provides significant benefits in terms of efficiency and noise reduction.
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

The Central Board of Secondary Education (CBSE) will now conduct two separate examinations for Mathematics in class 10 board examination starting from the 2020 session. The current Mathematics exam is termed Mathematics (Standard), and an easier version of Mathematics has been introduced, called as Mathematics (Basic).
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.
Two schools were at Norfolk: the Radar Materiel School on the Main Base, and the Fleet Service School at nearby Virginia Beach, Virginia. At Pearl Harbor Naval Base, there was a Fleet Service School that gave a three-month radar maintenance course. [33] The Radar School for Navy Officers was at the Massachusetts Institute of Technology (MIT ...
