Your Name Your Title Your Organization (Line #1) Your Organization (Line #2) Basics of Radar Joe Hoatam Josh Merritt Aaron Nielsen

Outline History How it Works Basic Equations Range Ambiguity Doppler Effect

History RAdio Detection And Ranging Heinrich Hertz experiments 1904 – Christian Huelsmeyer's demonstration 1940's – American and UK Research 1950's – Non-Military Usage 1958 – Doppler Radar

How Radar Works

Transmitter & Receiver Signal Reflection Measurement Different Uses Point vs Distributed Targets

Basic Equations

Range Ambiguity Pulse Repetition Frequency (prf) Too high – echoes from previous transmission increased Inaccurate Range Measurements

Doppler Effect

Velocities of Moving Objects Phase Shift
