12. Doppler velocity
Doppler Velocity Calculation:
Select ON or OFF to calculate the Doppler velocity.
SQI threshold:
Setup SQI (Signal Quality Index) threshold (0.00 to 1.00)
13. Signal processing
Rainfall intensity estimation method:
Select a Rainfall intensity estimation type.
・ Zh: Use horizontal amplitude information only.
・ Zh, Ah: Zh is calculated from the value that
corrected rain attenuation by the Ah
method.
・ Kdp+Zh: Use complex information, amplitude, and
Rainfall intensity estimation correction by EL:
Select ON or OFF to correct rainfall intensity estimation
by degree of elevation.
Output data range resolution [m]:
It is a data separation in range direction. If set this value
to 75 m, data will output every 75 m.
It recommends using that which has set on the
resolution of pulse setting in Table 2.7.
However, required data can not be acquired if the resolution of Output data range resolution is larger
than the set pulse
Antenna beam width (H) [deg]:
It is a half power width of main lobe on horizontal plane. (Not affected to physical beam width)
Antenna beam width (V) [deg]:
It is a half power width of main lobe on vertical plane. (Not affected to physical beam width)
TX power (H) [W]:
It sets the power apply to antenna. (Not affected to physical TX power)
Antenna gain (H) [dBi]:
This gain is according to the basic definition of horizontal, in which the antenna is compared to an
isotropic radiator. (Not affected to physical Antenna gain)
Antenna gain (V) [dBi]:
This gain is according to the basic definition of vertical, in which the antenna is compared to an isotropic
radiator. (Not affected to physical Antenna gain)
RX gain (H) [dB]:
It is the gain of whole receiver chain to horizontal. (Not affected to physical RX gain)
RX gain (V) [dB]:
It is the gain of whole receiver chain to vertical. (Not affected to physical RX gain)
K square value:
It is a parameter proportional to raindrop's refractive index. The default value for rain is 0.93.
ZDR offset correction [dB]:
Setup a value of Zdr to revise amplitude deviation of horizontal and vertical.
phase.
