Range detection and continuous wave
WebbRADAR stands for ‘Radio Detection And Ranging’ and is an active transmission and reception method in the microwave GHz range. Radar sensors are used for contactless detection, tracking, and positioning of one or more objects by means of electromagnetic waves. 1.2 How does radar detection work? WebbContinuous Wave Radar Chapter 13: Continuous Wave Radar 13 - 1 Dr. Sheng-Chou Lin Radar System Design Radar Types CW systems •CW radar - No range information - single target - Unambiguous velocity information •FM-CW systems - measure both range and velocity - broaden the transmitted freq. spectrum Pulsed Systems •Pulsed radar ...
