X-Band Radar, A Remote Sensing Technique To Detect, Track, And Warn Changes In Weather, Wave Climate And Ship Routing Services

An X-Band radar is a self-propelled, floating, towed radar system that is primarily used for detection, tracking, and early warning of aircraft in high seas or coastal waters. It uses an improved tracking method known as the Doppler shift and incorporates advanced radar techniques such as phase shifting, pulsing, and the Doppler Effect.

The X-Band radar system can be fitted to both surface ships and submarine and it can also be used for anti-submarine operations. It can detect, track, and classify the speed of moving objects within a range of about 400 km and can also use Doppler and other radar techniques to determine the position, velocity and direction of moving objects in higher altitudes and at various altitudes. In order to maximize the benefits of the system, it must operate on a regular basis. The radar can operate even during bad weather, with its onboard computer being able to override the automatic controls if necessary. Although it has been in service since the 1960's, it is still in use today by the U.S Coast Guard. In India, a new X-band radar made by Chennai-based Data Patterns, is being used to track extreme weather events during the northeast monsoon season.

X-band radar can operate at low frequencies by using a low-frequency amplifier, which allows it to be operated in the low-frequency ranges, and then when necessary, the low-frequency amplifier is turned on to boost the effectiveness of the radar. It is also able to detect targets at greater distances by using an inboard radar receiver and a fixed-frequency receiver system. The radar uses a number of methods to achieve low frequency operation: frequency hopping, variable-frequency hopping, and frequency division multiple access. Frequency hopping helps to achieve the lowest possible frequency by hopping from one frequency to another in order to detect objects at shorter distances. Variable-frequency hopping enables a single frequency to be switched rapidly between one frequency and another in order to detect objects at longer distances.

Pregnancy Testing Devices are proving to be revolutionary tool with hassle-free testing and rapid results

Image
Pregnancy Testing Devices are medical devices that aid in identifying the potential of pregnancy. It is mostly used by pregnant women for determining the exact time they missed their periods. Pregnancy Testing Devices come in different types like basal body membrane technique (BBMT), digital analysis, embryo transfer method (ETM), ultrasonic Doppler microform method (UDM), and hysterosalpingogram (HSG). Pregnancy Testing Devices is also calling pregnancy test kits.  They can also be termed as basal body membrane technique test kits. Pregnancy test kits are available in various online stores at affordable prices. The most common one is kits for basal body membrane technique (BBMT) and digital analysis. BBMT uses a wet mount for conducting the test whereas digital analysis requires no dry mounts. Some of the other methods of analyzing pregnancy tests include determining the LH level, HCG level, sugar level, cervical mucus, and viral detection. A pregnancy test can also be used for d...

Liquid Crystal Polymers are witnessing wide range of applications as Industry Leaders in Japan Develop Novel LCP Products

Image
Liquid crystal polymers (LCPs) are a category of aromatic polymers that are extremely inert and unreactive and also highly resistant to fire. LCPs are mainly useful in mechanical and electrical parts, food containers, and also other applications where chemical inertness is necessary. They are also used in plug connectors, transmission system components, lamp sockets, pump sockets, and sunlight sensors. The most recent technology to emerge as one of the most sought after polymeric materials is the LCD or Liquid Crystal Display.  This technology is now used in almost every commercial production process from the initial manufacturing stage right through to the final display unit of an electronic display. Liquid crystal polymers are currently used in the construction industry and are widely available as a wide range of goods. Polypropylene, polystyrene, and polyimide are popular building material which use these compounds to make various products including insulation, plastic, insulati...

Polydimethylsiloxane (PDMS): A Member of Polymeric Organosilicon Compounds Used In Various Industries Due To Its Versatility and Properties

Image
Polydimethylsiloxane (PDMS) is a compound that is commonly used for the development of contact lenses, but it has many other uses as well. Surfactants and foaming agents are among the many things that are made from PDMS. Other uses include, the treatment of petroleum jelly and rubber. The chemicals used in the manufacture of cosmetics and medicines may also be derived from PDMS. The production facilities for PDMS in Europe are located in France, Germany and the U.K. In Germany, PDMS is classified as “slightly water polluting”. It was not that long ago that scientists thought there might be some connection between the use of polydimethylsiloxane in cosmetics and the development of allergic reactions. Scientists have since conducted studies and discovered that there actually are connections between the use of this chemical agent and the development of eczema and allergic reactions. The link between cosmetics and skin irritation and allergy is a result of the fact that the ingredients in...
