Microwaves are used in the medical field, military, aviation industry, and weather reporting. Microwaves can be used to detect metal (such as weapons), they can be sent through walls to see if there is something on the other side of it without even having to open up the wall to get there, and they …
What is ARPA? ARPA is the abbreviated term for Automatic Radar Plotting Aids. This system was developed by Rokycany Research Center in Czechoslovakia to replace manual radar plotting. The ARPA consists of computer workstations, called operator terminals which are located next to each radar screen for each sector. The data about ownship are entered …

Underwater ventures by human beings are not new. The first underwater vessel was invented back in the 17th century. Although they were fascinating, there always lacked a precise way of communicating with other underwater vessels. Enter SONAR technology. SONAR, which stands for Sound Navigation And Ranging, isn’t quite a new technology, either. The first underwater …
Storm chasing is an exciting yet dangerous activity. Whether you’re a professional TV meteorologist or want to do an adventure, choosing radar for storm chasing is essential. It helps detect the size, duration, direction, and speed of the storm to avoid unwanted problems. After evaluating weather patterns before moving out of your home, the next …
Years ago, marine radars were only mounted on large boats operated by seasoned sailors. They used to be bulky and not always compatible with the average systems used on boats. These days, even amateur sailors on smaller boats with relatively basic systems can easily avail of lighter, system friendly versions of marine radars to help …
Yes, lidar can penetrate water but can be quite a challenge. Mainly due to various limitations such as refraction and light absorption. Greenlight (infrared wavelength of 532nm) from Lidar sensors can penetrate water the best and farthest due to its wavelength. It can penetrate ocean water of up to hundreds of meters (up to 300m). …
Remote sensing, surveying, and monitoring have, in the last few years, reached new heights with the power of the LiDAR technology. The proliferation of LiDAR, which stands for Light Detection and Ranging, is now seen in multiple industries including forestry, disaster management, weather prediction, construction, archaeology, autonomous vehicles, and many more. It is important to …
Submarines were first built in the 19th century and rose to popularity during the First World War. The extraordinary capability of these vessels to remain beneath the surface of the water for long periods and enter enemy waters undetected made them indispensable in warfare. Apart from the navy, submarines have also found their use in …
