Study Notes

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'.
