Radar Principle. The electronic principle on which radar operates is very similar to the principle of sound-wave reflection. If you shout in the direction of a sound- reflecting object (like a rocky canyon or cave), you will hear an echo. If you know the speed of sound in air, you can then estimate the distance and general direction. Physical fundamentals of the radar principle - Introduction of the chapter basic principle of operation. Radar Principles. &. Systems. With your facilitator,. LT Mazat. I. Learning Objectives. A. The student will comprehend the basic operation of a simple pulse radar system. B. The student will know the following terms: pulse width, pulse repetition frequency, carrier frequency, peak power, average power, and duty cycle.
A radar system makes use of high-speed electromagnetic waves to determine the location (distance), the velocity, the direction being travelled, and the elevation ( altitude) of both stationary and non-stationary objects. These objects can include weather formations, motor vehicles, ships, aircraft, spacecraft, and even terrain. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or. RADAR PRINCIPLES. I. Introduction. Radar is a general technique, willcli has a wide range of \, ariability depending o11 the type of targets to be measured. A radar can be designed to IlTeasure a bullet, \\, bile another may observe a planet. The radio frequency spectrum employed also spreads out over inariv decades.
The aim of this course is to provide the students with an understanding of the fundamental principles, design and analysis of radar systems. Pulsed RADAR sends high power and high frequency pulses towards the target object. It then waits for the echo signal from the object before another pulse is send. The range and resolution of the RADAR depends on the pulse repetition frequency. It uses the Doppler shift method. The principle of RADAR detecting moving. 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.
