    • 2. Radar Radar Radar: Radar is the first word in the world. Radio waves are used to detect the location. Working principle: Electromagnetic signal pulses are sent and the energy transmitted by the radio waves is reflected in the object after reaching the object, these reflected signals are called echo. The intensity of the echo is ready for the radar and the time to return is multipurpose. The determinant of the object appears. It is also necessary that the echo that is reflected from the electromagnetic signal sent by the radar is above a certain level. This level is called the threshold value.
    • 3. Areas Of Radar Areas Of Radar Radars are used in civil and military areas. In the areas of air traffic control and flight management in civilian use, traffic management systems, ship traffic in the seas, navigation and weather radar and search and rescue, security, and vehicle speed sensors; Surveillance in military use, observation, target classification and ballistic identification, early warning systems missile defence, air strike warning, guidance systems, location determination in operations, simulation and modelling tasks are used.
    • 4. Areas Of Radar Areas Of Radar Basically, we can specify radar types as pulse radars and continuous wave radars. Although impact radars are the most widely used radar type, they operate according to the basic principle we have described above, ie the system logic that determines the target information by sending the radio waves and using the time elapsed with the reflection.
    • 5. Areas Of Radar Areas Of Radar They usually accommodate a single antenna for sending and receiving. After sending the wave pulses, they are reflected in the target and wait for it to return. The waves take 300 min 1 microsecond. If the reflection of a wave coming out of the antenna comes after 2 microseconds, we find that the target is 300m away.
    • 6. Areas Of Radar Areas Of Radar Continuous wave radars use two different antennas as transmitter and receiver and operate according to the principle of Doppler shift. With this method, it can be difficult to determine the range of a target and distinguish the two targets.
    • 7. Synthetic Aperture Radar (SAR) Synthetic Aperture Radar (SAR) The waves that send and reflect waves from different and multiple points are the radars of obtaining the image of the scanned area by functioning in accordance with the physical structure of the world. An image obtained from ASELSAN SAR Radar.
    • 8. Radar Resolution Radar Resolution The meaning of the resolution is the ability to distinguish two targets close to each other. There are two different resolution variables. Azimuth and range resolution. Azimuth is the effect that the two targets perceive these targets as a single target when they are at equal distances with the radar antenna and are close to each other. If the range is the same distance from the radar station of the two targets, one of the two targets before the other reaches the radar, the radar perceives it as a single target Let's give an example of a few radar types without too much detail.
    • 9. Radar Resolution Radar Resolution The Arthur radar has a passive phased array antenna and can detect the trajectory of a missile with high accuracy. The antenna can scan both height and azimuth angles. It can detect dozens of targets at the same time. GreenPine Radar This radar has a phased array antenna and is located in the C band between 500 MHz and 1000 MHz frequency of the signals it sends. It can scan an average range of 500 km...
