radar band造句

• The radar band as frequencies between 300 MHz and 1 GHz.
• They are wide-band beacons which transmit either continuously or periodically on the radar bands.
• Nakidka is designed to reduce the probabilities of an object to be detected by Infrared, Thermal, Radar-Thermal, and Radar bands.
• "' FuG 223 "': A family of passive airborne receivers tuned to various radar bands such as Freya and W黵zburg.
• "' Ramarks "'are wide-band beacons which transmit continuously on the radar bands without having to be triggered by an incoming radar signal.
• Two other IEEE radar bands overlap the ITU UHF band : the L band between 1 and 2 GHz and the S band between 2 and 4 GHz.
• Depending on the market the RWR system is designed for, it can be as simple as detecting the presence of energy in a specific radar band ( such as police radar detectors ).
• Raytheon's X-band, active-array SPY-3 Multi-Function Radar ( MFR ) offers superior medium to high altitude performance over other radar bands, and its pencil beams give it an excellent ability to focus in on targets.
• Users can disable or enable any radar band of their choice, including laser, set muting options for K-band radar, enable extra sensitivity for Ka-band, enable POP radar detection, activate European radar modes among other options.
• "The Pentagon was very concerned that wireless devices were popping up in what has historically been a radar band, " said Steven Price, deputy assistant secretary of defense for spectrum and command, control and communications policy.
• P band is sometimes used for K u Band . " P " for " previous " was a radar band used in the UK ranging from 250 to 500 MHz and now obsolete per IEEE Std 521.
• According to Nii Stali, the designers of Nakidka, Nakidka would reduce the probabilities of detection via " visual and near-IR bands by 30 %, the thermal band by 2-3 fold, radar band by 6 fold, and radar-thermal band to near-background levels.
• "' Low-frequency radar "'is radar which uses frequencies lower than 1 GHz such as L-band, UHF, VHF, and HF, as opposed to the usual radar bands, which range from 2 GHz and up, and the maximum is 40 GHz . The radar cross section of any target depends on the radar transmitted frequency.
• If Navy requirements favor a UAV optimized for permissive ISR over broadband stealth, the Sea Avenger may better meet them, as it was originally pitched as having a reduced signature to be " stealthier " than other aircraft . Broadband stealth that is effective against low-frequency radar bands like VHF and UHF usually are present in a flying wing design.
• As of Dec 2014 the FCC was extending the limited success of television band spectrum sharing ( TV white space ) into other bands, significantly into the 3550-3700 MHz US Navy radar band via a three tier licensing model ( incumbent, priority, and general access ) while Europe has been pursuing an authorized shared access ( ASA ) licensing model.
