When processing dual-polarization data, the IQ2-DSP also produces:
• Differential Reflectivity (ZDR)
• Differential Phase ( Φ DP)
• Specific Differential Phase (KDP)
• Correlation Coefficient ( Ρ HV)
• Linear Depolarization Ratio (LDR)
The standard IQ2-DSP algorithms for the horizontally and vertically polarized channels include
but are not limited to the following:
• Thresholding: Noise, SQI 1& 2, SIGPOW, CCOR, & RHOHV
• Speckle Remover: Z, V, W, & DP
• Averaging: Time and Range
• Doppler Clutter Filters: Time- and Frequency- Domain
• Pulse-Pair Processing
• Discrete Fourier Transform (DFT) Processing
• Staggered PRT Processing or Dual PRT (DPRT)
• Second Trip Processing
• Range-Doppler Dilemma.
Each moment for the current mode of operations routes to the EDGE radar product generator for
further processing and display.
The IQ2-DSP produces the IF transmit pulse input to the RF/IF Up-Converter Assembly in the
Modulator Cabinet. The IQ2-DSP is the master radar synchronizer using a very stable, accurate
trigger generator to produce the system control and timing signals during normal REMOTE and
LOCAL operations.
1.1.2.2. IQ2 DSP PCIe Board (Unit 1 A2 A2)
The EEC IQ2-DSP utilizes a PCIe used for signal processing deployed in the Control Cabinet.
This IQ2-DSP Host Computer and PCIe card design allows for the highest performance available,
as well as for flexibility in adapting to various radar system configurations. The IQ2 IFD is in an
RF Enclosure above the elevation rotary joint. This configuration ensures system optimization
for low transmit and receive losses, as well as for very high data throughput.
1.1.2.3. IQ2 Connector Panel (Unit 1 A2 A3)
The connector panel allows the IQ2 Digital Signal Processor to connect with and communicate
with the IQD-IFD and the EDGE workstation.
1.1.3. Keyboard Video Monitor (Unit 1 A3)
The Keyboard/Video Monitor (KVM) is a control unit that allows access to multiple computers
from a single keyboard, video monitor, and mouse console. The configuration of the KVM allows
it to control the RCU and IQ2-DSP. A local host computer (EDGE) also connects to the KVM.
The cover had a built-in LCD display, and the keyboard and touchpad are built-in to the base.
The KVM module fully integrates into the cabinet and can slide out and open for use.
