Algorithm

Description

Processing options

• Azimuth averaging: 2 ... 1024 pulses
• Corrections for gaseous attenuation and1/R2
• Dual-polarization: Alternating, Simultaneous, H-only, V-only
• Clutter filters: Fixed/Adaptive GMAP in frequency domain, or IIR

time domain

• High sensitivity Rhv STAR mode processing: >3dB improvement in

detectability

• Pulse integration up to1024
• Range de-aliasing: random phase
• Scan angle synchronization for data acquisition
• Up to 4 pulse widths
• Velocity de-aliasing: dual PRF velocity unfolding at 2:3, 3:4, and 4:5

for 2X, 3X, or 4X velocity unfoldings

Data quality thresholds

• Signal-to-noise ratio (SNR)—Used to reject bins having weak

signals; typically applied to dBZ

• Signal quality index (SQI)—Used to reject bins having incoherent

signals; typically applied to mean velocity and width

• Clutter-to-signal ratio (CSR)—Used to reject range bins having very

strong clutter; typically applied to mean velocity, width, and dBZ

• Speckle Filter—Removes single-bin targets such as aircraft or noise

and fills isolated missing pixels
