Pick an example of radar and explain how it works using at least one diagram or picture. [5 marks]

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

Future mobile wireless sensors networks technology such as smart dust may seem like science fiction but its making its way from research laboratory to enterprise.

Affordable mobile communication for civilian and military applications is greatly enhanced by the significant investments in infrastructures such as cellphone towers and repeaters. However, such infrastructures cannot be provided for ad-hoc communication systems and the network connectivity for such systems is greatly degraded by the adverse effects of the communication channel such as multi-path fading, attenuation, non-line-of-sight, etc. As a result, operation at longer wavelengthes (UHF and VHF) is preferred for ground communication between army vehicles to decrease path-loss and bypass obstacles. Also because of the issues related to near-earth wave propagation, vertical polarization is the preferred choice to achieve minimum path-loss.

Radar works by transmitting strong but short pulses of radio energy into the air in a certain direction using whats called an antenna these pulses bounce off metallic objects such as ships or aircrafts they bounce back to the antenna these signals are then converted to a signal which is shown on a screen.

Radar is an object-detection technique that uses radio waves to conclude the distance, course, elevation, or speed of varying objects. Radar was originally used to sense aircraft, motor vehicles, ships, guided missiles, weather developments, and different terrains. The radar dish or antenna broadcasts beats of radio waves or microwaves that recoil off any object in the path of the signal. The object returns a minuscule portion of the wave's original energy to a

If you go into account why a quite cave and you yell, you may hear your voice coming back to you. That's what the radar machine does. It Emmett emits that radiowave just like your yell, and it interprets the waves when they bounced back to the machine. A radio wave is no electromagnetic radiation. All radars have four main parts; the antenna, the indicator (which is a display screen), The transmitter, and the receiver. These parts are used in the cycle. The cycle starts with the transmitter. The transmitter amidst the way. The waves can travel for miles and when it reaches the target, the wave Downs is back to the radio system and is detected by the antenna and get sent to the receiver. The receiver then take the information and it Hanses it. The information is commonly displayed on the screen called the indicator that displays the data. Most indicators are ppi indicators, also known as Plan Position Indicators. This is virtual map that has in the center of the location of the radar and will display the target according to its proximity to the radar system. The position of the target is called

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Incorporated Circuits (Ics) are accessible at Mouser Electronics from industry heading makers. Mouser is an approved wholesaler for some incorporated circuit makers including Analog Devices, Atmel, Cypress, Fairchild, Free scale, IDT, Maxim Integrated, NXP, ON Semiconductor, Stmicroelectronics, Texas Instruments, & a lot of people more.

In the recent pass, both academia and industry field have shown a substantial general interested in wireless medium communications, Ultra-wideband (UWB) transmission applications [1, 2]. Having numerous advantages such as high data rate on very low power and short distance range technology makes UWB as a fascinating technology. Those benefits placed UWB as an interesting technology for military and medical applications that uses radar and information sensing.

Radar is a tool that uses microwave radiation to find out and locate faraway objects that are usually shown on the screen.

Radar is an acronym and is known as Radar Detection And Ranging. Radar system is used to detect the range or velocity of an object by using radio waves. Radar is a detection system for an object which uses radio waves to detect range, angle and velocity of objects. Radar uses radio waves or microwaves which reflects back from any object in their path. Radar transmitter and receiver typically has same system which determines the object properties by receiving and processing these reflected waves.

O1) Develop, test, and quantify performance of data coding methods to improve signal-to-noise ratio of backscatter communication systems in strong multipath and Doppler environments. Data coding has been shown to improve the performance of backscatter systems with a low signal-to-noise ratio (SNR) for

Radio Detection and Ranging (RADAR) is a sensor used in the automotive domain to derive speed and distance information. Now we will discuss on the principle of working, its classification and sub-systems used for processing. Currently we used frequency modulated continuous wave (FMCW) RADARs and so this type will be elaborated here.

In this project we have discussed about the basic information related to Field Effect Transistors (FET). Starting from the history of FET and its development over the years. It is a three terminal unipolar transistor involving single carrier type operation. Next, we discussed about its composition and basic operation principle. We also focussed on different types of FETs commercially used worldwide and their significance at various level of Electronic industry. Scientific papers on FET were read thoroughly and various advancements were noted. It was realised that modification in FET can bring about tremendous change in characteristic of the device. Though the advancement bears a numerous drawbacks and requires future research, a step closer to low cost and environment friendly device has been initiated. The advantages and disadvantages were also discussed precisely to help us understand the selection of various devices in different circumstances. Lastly, future prospect of FET is discussed that can lead to promising advancement in the field of electronics.
