101seminartopics.com ABSTRACT Topic: - MILITARY RADARS RADAR (Radio Detection and Ranging) is basically a means of gathering information about distant objects by transmitting electromagnetic waves at them and analyzing the echoes. Radar has been employed on the ground‚ in air‚ on the sea and in space. Radar finds a number of applications such as in airport traffic control‚ military purposes‚ coastal navigation‚ meteorology and mapping etc. The development of the radar technology took place during the World

MEDICAL APPLICATIONS OF ULTRASONICS The applications of ultrasonics in the medical field have involved analysis and treatment. The developments in the medical field appear to be very promising. The effect of ultrasonics on tissues has been investigated. The heating and mechanical effects have been isolated. The conclusion is that there is an effect outside of the heating effect. The effects of the changes produced by high intensity sound upon the central nervous system has been investigated

Uwb Radar And Applications CHAPTER 1 INTRODUCTION UWB stands for ultra wideband. The basic concept is that frequency is meaningless. UWB systems use electromagnetic pulses‚ just pulses‚ not short wave-packets. Pulse repetition frequency (PRF) couldnot be declared‚ as is not a correct figure of electromagnetic spectrum occupation. PRF is typically in the range of 1 to 50 MHz.The pulse repetition period ismodulated to carry information or coding. A precise frequency description of UWB emission could

CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted‚ reflected off a target and then returned as an echo. Radar makes use of a phenomenon

Development of Radar Radar was developed was developed between 1935–1940 independently in several countries as a military instrument for detecting aircraft and ships. One of the earliest practical radar systems was created from 1934 to 1935 by Robert Watson-Watt. Although the technology evolved rapidly during World War II‚ the radar improved immensely following the war‚ the principal advances being higher power outputs‚ greater receiver sensitivity‚ and improved timing and signal-processing circuits

GENERAL RADAR DISPLAY TYPES There are two types of radar displays in common use today. RAW VIDEO Raw video displays are simply oscilloscopes that display the detected and amplified target return signal (and the receiver noise). Raw video displays require a human operator to interpret the various target noise and clutter signals. On the left hand display of Figure 1‚ an operator could readily identify three targets and a ghost (a ghost is a phony target that usually fades in and out and could be

Radar From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For other uses‚ see Radar (disambiguation). A long-range radar antenna‚ known as ALTAIR‚ used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll. Israeli military radar is typical of the type of radar used for air traffic control. The antenna rotates at a steady rate‚ sweeping the local airspace with a narrow vertical fan-shaped beam‚ to detect aircraft at all
