What is a passive radar?
Passive radar is a radar system that only accepts transmission and income alternation. These systems are used in different environments and have a number of advantages that make the objectives of interest for many military technology developers. Passive radar is basically a very finely tuned pair of ears, sensitive to high -frequency radio waves, rather than sounds that can hear by a human ear. For example, a ship could use a radar to find potential enemy ships in this area. Unlike Sonar, which uses the sound, the radar uses high -frequency radio waves.
Passive radar has the same ability to pick up microwave energy but does not carry it. Instead, it uses reflections from other objects APPLIGHT SOURCE to collect information about the goals, rather working passively than actively to identify objects in its surroundings. Using this information, the device can provide information about the scope, speed and location that can be used for decision -making. For example, a passive radar on the aircraft could be usedTo identify other aircraft in this area for the purpose of avoiding them.
From a military point of view, it is a clear advantage of a passive radar that it is secret. Because it is not transmitted, it may be difficult for the enemy to locate because there is no signal to monitor. Instead, the passive radar simply sits and waits for signals of interest. Although a passive radar field is identified, it may be difficult to get stuck because there is no way to find out which frequency uses, although the tactics can be used to spoof for confusing. The use of passive hidden radarum can improve the security of the mission and allow people to have access to radar data continuously.
Passive radar detection of interest goals is also less expensive and complex than working with an active radar system. This makes the implementation cheaper and can make it attractive in the settings where the radar must run quickly. WellDifferent things can be used as a passive radar reflector, allowing technology to use different objects in its vicinity to collect information.
