JRC JMA-7725-6 - Setting Transmission Repetition Frequency

8 – 31
8.5
8.5.3.6 Setting Transmission Repetition Frequency
• Select one of three transmission repetition frequency types.
• The transmission repetition frequency relates to the sensitivity and power consumption (life span of
magnetron).
• When the transmission repetition frequency is high, the sensitivity improves, however, the power
consumption also increases, reducing the life span of the magnetron.
• When the transmission repetition frequency is low, the power consumption decreases, increasing the
magnetron life span, however, the sensitivity deteriorates.
• The radar trails reduction processing demonstrates the effect when the transmission repetition frequency
is "ECONOMY".
NORMAL : Balanced setting for the sensitivity and the life span of the magnetron.
HIPOWER : Hipower setting; use for detecting small targets.
However, the life span of the magnetron is reduced.
ECONOMY : Economy setting. The maximum life span of the magnetron can be increased.
However, the sensitivity deteriorates slightly.
Use this mode at radar trail fine line processing.
When the fales echoes appear by anomalous propagation, using this mode reduces
those fales echoes.
See section “6.4 [V] Anomalous Propagation”.
