Outline Objective About PR-2 PR-2 vs Nexrad Observations Recent Ideas Next Up….

Objective Modify Source Code to our needs: Raw Data Display Resolution Data Resolution Data Transfer from Aguadilla – UPRM Validate Radar Data Pulse width modification?? Modify Source Code to our needs: Raw Data Display Resolution Data Resolution Data Transfer from Aguadilla – UPRM Validate Radar Data Pulse width modification??

About PR-2 Radar donated by EWR Weather Radar Systems. Model: EWR 600 Radar donated by EWR Weather Radar Systems. Model: EWR 600 Tx/Rx Frequency: GHz (± 30 MHz) Power Output: 4kW peak Pulse Width: 4µs Range: 40Nm (for our purposes) PRF: 119 Hz (± 10 %) Receiver Gain: 135dB Tx/Rx Frequency: GHz (± 30 MHz) Power Output: 4kW peak Pulse Width: 4µs Range: 40Nm (for our purposes) PRF: 119 Hz (± 10 %) Receiver Gain: 135dB Antenna Flat Plate (Slotted Waveguide) Size : 18” HPBW: 5.5˚ Gain: 31.0 dB Side Lobes : -25 dB Tilt: 0˚ to 15˚ Antenna Flat Plate (Slotted Waveguide) Size : 18” HPBW: 5.5˚ Gain: 31.0 dB Side Lobes : -25 dB Tilt: 0˚ to 15˚ System Specifications

Radar Data Interface

PR-2 vs Nexrad Comparison Data Comparison: EWR vs Nexrad

Observations ~ 30˚

Observations cont… Google Earth

Observations cont… Nexrad starts ~ 0dBz vs 23dBz. Missing Light Rain?

Recent Ideas Looking into modifying the transmitted pulse width. Benefits: Gain coverage within Aguadilla. Ease the possibility of an external calibration (if in need). Looking into modifying the transmitted pulse width. Benefits: Gain coverage within Aguadilla. Ease the possibility of an external calibration (if in need).

Next Up… Modify EWR Source Code. Establish DSL – File Transfer to UPRM. Check for installation errors. ** Modify pulse modulation for better coverage. Crucial Needs… EWR Source Code Update: EWR Agreed to give us code. It’s in due process.
