Basic Radar Terminologies Prelims 1

Radar Terminologies

• The aim of teaching basic radar terminologies is to understand the fundamental concepts and principles of radar systems.

Radar Information Resource

• The website mentioned as a reference for radar information is not specified in the text.

Radar Terminology Definitions

• 'Freq' in the context of radar terminologies refers to frequency.
• The term that relates to the ability of radar to distinguish between two closely spaced targets is range resolution.
• The phenomenon that occurs under specific atmosphere conditions, allowing the detection of targets well beyond the normal radar line-of-sight, is called 'anomalous propagation'.
• 'Doppler Beam Sharpening' aims to enhance range resolution in radar systems.
• 'Pulse Width' in radar terminology refers to the duration of a radar pulse.
• 'Dead Time' represents the period during which a radar system is unable to detect targets due to the transmission of pulses.
• The significance of 'Min Range' in radar operations is it represents the minimum range within which a radar system can detect targets.
• 'Range Resolution' measures the minimum distance between two targets that can be distinguished as separate targets in a radar system.
• The primary factor that determines the dwell time of an antenna beam is the speed of the antenna rotation.
• 'Pulse Recurrence Frequency (PRF)' in radar systems refers to the number of pulses transmitted per second.
• Increasing the Pulse Width in radar systems increases the average power of the radar signal, thus enhancing detection capabilities.
• The primary purpose of Doppler Beam Sharpening in radar systems is to enhance range resolution.
• The main characteristic used to define 'Beam Width' in radar terminology is the angle between the half-power points of the main lobe.
• The term used to describe the number of cycles in one second in radar terminology is 'frequency'.
• The basics of electrical engineering, including important terms related to radar, help in understanding radar systems and their applications.

Radar Terminology Sequence

• The term discussed after 'Dwell Time' is not specified in the text.

Radar Acronym

• 'MTBF' stands for Mean Time Between Failures in radar terminology.

Radar Target Identification

• The radar term that refers to the ability to differentiate between primary and secondary trace echoes is 'clutter suppression'.
