Communication system,Michael Kors outlet, the ship is equipped with the function of many different radios. When the frequency standard signal and is used to send notification of the potential long -wave for the 30 to 250 sea miles range shore -to-ship contact longwave low frequency, intermediate frequency wave communications for less than 30 nautical miles from the tactical and rescue communications for short- distance high frequency communications and tactical communications for tactical command ( air, ship, shore, etc. ) VHF FM communications radio equipment and other five. Navigation system is to ensure the safe navigation of vessels, are able to ship weapons systems, command systems to provide accurate and important information warships heading, speed, latitude and longitude, etc. in real time, and includes a ship where the water depth, wind speed, wind direction, temperature and humidity, and other information.

Of course,discount Michael Kors, this feature also is not very strong, both hardware and software capabilities, and high-speed computers can not be compared to future generations, but in this day and age is considered a super- high-tech. Radar is a radio- ranging career and development due to come out, work in different ways according to a continuous wave and pulsed two kinds of radar. Refers to intermittent pulsed radar transmitter power louis vuitton factory outlet pulse signal, the pulse interval of time to accept the target echo signal reflected back, after more accurate estimates derived target distance.

Therefore, continuous wave radar a little more advantages compared to the former, it is the use of the Doppler effect of moving targets, the non-modulated continuous wave radar can target with any speed carried a considerable distance speed. Limited strength of the sunglasses outlet electronics industry and the level of autonomous half of the twentieth century, still far, it is nothing phased array radar, over the horizon radar, enemy Michael Kors outlet recognition technology too difficult for radar equipment, Nanning No. the only two radar equipment. The first one is used for a certain distance air threat detection, but does not require too much precision and resolution of the surveillance radar.
