RADAR is an acronym derived from radio detection and ranging is electronic equipment for detecting and tracking objects. Radar uses radio waves to determine the direction, range, altitude or speed of an object. It is used in detection of spacecraft, ships, aircraft, missile and vehicles. RADAR uses radio energy for ranging and detection of an object. They are widely used in weather forecasting, meteorology and geology purposes. Initially RADAR was developed for military and defense purposes. However, with technological advancement such as greater receiver sensitivity and high power output it can also be used in several other applications such as tracking missiles and detecting aircrafts
In RADAR, short bursts of radio energy are transmitted and reflected from the target as an echo. The radar signals are generated by the transmitter and received by a sensitive receiver. Directional antennas are used in RADAR for the purpose of transmitting the pulse and receiving the echo. The frequency range used by RADAR is divided into two groups. The first group includes X-band with a frequency range of 9,300 MHz to 9,500 MHz. The second group is S-band having frequency range of 2,900 MHz to 3,100 MHZ. Different techniques used in ranging and detection include bi-static, mono-static and quasi-mono-static. In bi-static technique, the transmitter and receiver antenna are located at different locations whereas in mono-static both the antennas are co-located for target. In quasi monostatic the transmitter and receiver antennas are slightly separated but appear as co-located.

RADAR shows application in air traffic control, antimissile systems, ocean surveillance systems, space surveillance, aircraft anti-collision systems, radar astronomy and air-defense systems. Highly advanced radar systems are used for digital signal processing and are capable of extracting useful information from high noise level.
High defense budgets of different countries and increasing demand for economic and security issues are driving the demand RADAR market. Additionally, technological advancements and increasing demand for ranging and detection of objects is fuelling the growth of the market. However, adverse climate conditions affect the range of RADAR which poses a key challenge for the market. Moreover, technological developments such as phased array systems and active electronically scanned array systems offer potential opportunities for the market.
RADAR market can be segmented on the basis of application, types and waveform. RADAR has application in several industries such as military and defense, aviation, marine and space industry. In aviation industry, aircrafts are equipped with radar to provide altitude and weather information. Marine Industry uses radar to measure the distance between the ships and to navigate a ship. Applications of RADAR in military and defense is expected to witness tremendous growth over the forecast period. Different types of RADAR available are ground based, air borne, naval and space based radar. RADAR operates on different waveforms including continuous wave and pulsed wave. Further, continuous waveform includes frequency modulated continuous waveform and pulsed wave is classified into coherent and non coherent waveforms.
