| The low height of the radar mast makes it difficult to acquire and lock onto a target while maintaining a safe distance. |
|
| As such, fine line patterns within weather radar imagery, associated with converging winds, are dominated by insect returns. |
|
| Wind farms can interfere with ground radar systems used for military, weather and air traffic control. |
|
| The large, rapidly moving blades of the turbines can return signals to the radar that can be mistaken as an aircraft or weather pattern. |
|
| The US military is using wind turbines on some bases, including Barstow near the radar test facility. |
|
| Wind turbine blades using stealth technology are being developed to mitigate radar reflection problems for aviation. |
|
| As well as stealth windfarms, the future development of infill radar systems could filter out the turbine interference. |
|
| Wallace of the army radar Interception Unit, had called for his assistance. |
|
| He was to attempt to enter the radar station and learn its secrets, accompanied by a small unit of 11 men of the Saskatchewans as bodyguards. |
|
| Many of the German radar stations on the French coast were destroyed by the RAF in preparation for the landings. |
|
| The term radar has since entered English and other languages as a common noun, losing all capitalization. |
|
|
|
| Other systems similar to radar make use of other parts of the electromagnetic spectrum. |
|
| He also got a British patent on September 23, 1904 for a full radar system, that he called a telemobiloscope. |
|
| Given all required funding and development support, the team produced working radar systems in 1935 and began deployment. |
|
| Later, in 1943, Page greatly improved radar with the monopulse technique that was used for many years in most radar applications. |
|
| In port or in harbour, vessel traffic service radar systems are used to monitor and regulate ship movements in busy waters. |
|
| A radar system has a transmitter that emits radio waves called radar signals in predetermined directions. |
|
| The radar signals that are reflected back towards the transmitter are the desirable ones that make radar work. |
|
| Although the reflected radar signals captured by the receiving antenna are usually very weak, they can be strengthened by electronic amplifiers. |
|
| More sophisticated methods of signal processing are also used in order to recover useful radar signals. |
|
| Radar absorbing material, containing resistive and sometimes magnetic substances, is used on military vehicles to reduce radar reflection. |
|
| The extent to which an object reflects or scatters radio waves is called its radar cross section. |
|
| This can degrade or enhance radar performance depending upon how it affects the detection process. |
|
| Doppler shift depends upon whether the radar configuration is active or passive. |
|
| When the reflector is moving at right angle to the radar beam, it has no relative velocity. |
|
| Vehicles and weather moving parallel to the radar beam produce the maximum Doppler frequency shift. |
|
| For a transmitted radar signal, the polarization can be controlled to yield different effects. |
|
| Reflected signals decline rapidly as distance increases, so noise introduces a radar range limitation. |
|
| Noise typically appears as random variations superimposed on the desired echo signal received in the radar receiver. |
|
| In modern radar systems, the internal noise is typically about equal to or lower than the external noise. |
|
| Some clutter may also be caused by a long radar waveguide between the radar transceiver and the antenna. |
