Radar reflectors are devices attached to boats to make them more visible on radar. They consist of metal pieces that reflect radar signals, making smaller boats more visible to larger ones. Reflectors are available in different styles and designs, and it is important to mount them high on the mast for maximum visibility. A radar […]
A radar altimeter measures an aircraft’s absolute altitude above the ground by directing radio waves at the ground and reading the reflected signals. It is an essential flight aid and part of the ground proximity warning system, providing accurate ground clearance and runway clearance readings. Radar altimeters have limited range but are critical for early […]
Primary radar uses radio waves to detect the distance and speed of objects in the air or on water. Antennas focus the signal in a specific direction. Transponders improve accuracy by sending out a stronger signal with aircraft information. Radar can also track weather and detect possible tornadoes. A primary radar system sends out a […]
Imaging radar uses radio waves to create three-dimensional images of targets, even through obstructions like clouds and forests. It has various applications, including in archeology and aerial surveying. Skilled technicians are needed to operate and interpret the data collected. An imaging radar is radar equipment used for imaging. Radar can be used in a variety […]
Radar domes protect radar equipment from the elements and people from rotating antennas. Radar devices use radio waves to identify objects and often require large dishes. Radar domes also protect dishes and electronics from dirt, rain, and ice. They keep people away from moving dishes and optimize surfaces exposed to air friction. Aircraft use streamlined […]
Pulse radar emits energy to detect objects and measures the time it takes for the energy to bounce back to determine distance. There are two types: simple pulse radar and pulse Doppler radar. The latter is more accurate for detecting moving objects. All pulse radar systems require a transmitter, antenna, receiver, and interface. Pulse radar […]
Tracking radar uses electromagnetic energy to locate and follow a specific target, such as aircraft or storm systems. It can be used for military purposes, monitoring air traffic, and weather forecasting. Modern tracking radar includes computer programs to reduce manual operations and operator error. Interference can come from materials resistant to detection, severe weather, and […]
Radar signals are radio waves used to detect objects in the atmosphere or underwater, and are used for weather and air traffic monitoring. The signals start from a transmitter and bounce back to a receiver, indicating an object’s distance, speed, and altitude. Radar is also used in military applications, but can be avoided through the […]
Monopulse radar is less prone to signal strength changes and jamming than cone scan radar. It splits its beam into two signals and compares them to determine direction accurately. The display consists of two overlapping lobes, providing high pointing accuracy. Monopulse radar produces signals with different polarities, making jamming difficult. A monopulse radar is a […]
Passive radar systems receive but do not transmit signals, using reflections from other objects to identify targets. They are stealthy, less expensive and less complex than active radar, and can use a variety of objects as reflectors. A passive radar is a radar system that receives only, instead of alternating transmit and receive. These systems […]
Radar alerts are used by managers to detect unusual patterns in stock trading and potential takeover attempts. Companies may contract specialized firms to monitor market activity. Managers can use the information to prevent a loss of control over the company and protect shareholder interests. Companies that offer radar alert services are known as shark watchers. […]
