ABSTRACT
Chapter 1 Radar Fundamentals
1.1. Radar Classifications The word radar is an abbreviation for RAdio Detection And Ranging. In
general, radar systems use modulated waveforms and directive antennas to transmit electromagnetic energy into a specific volume in space to search for targets. Objects (targets) within a search volume will reflect portions of this energy (radar returns or echoes) back to the radar. These echoes are then processed by the radar receiver to extract target information such as range, velocity, angular position, and other target identifying characteristics.
