Detections towards end of Day 1

HOSR detection at 14:55

HOSR detection at 13:33 GMT

SILD detection at 13:20 GMT

SeaStreak NJ

The ferry passed in front of the SILD site at 13:25 GMT.  Erick could see it in range cell 6 of SILD

Low Range at SEAB

The Bragg at SEAB dropped off after range cell 12.   I turned off the enhanced blanking at 12:45 GMT.  That improved the range a little.  Bragg now out to range cell 20.  The spectra has less noise and clutter.

First possible target

The Thomas Jefferson

The signal is more in loop 2 and monopole which makes sense that the ship is to the left of the radar when looking to sea.

DHS Experiment Day 01

We’re conducting the first exercise today of the NY Observatory for the CSR grant.   The SILD, SEAB, HOSR, HOOK HF Radar sites are operational.  The BRZY site is not working.  It was sent back to Codar for repairs.  The SILD Tx and Rx were also sent back to Codar for repairs.  We are using the multi frequency system at SILD in its place.

The current map for the harbor looks decent without BRZY.

SILD     25.1 MHz    -100.7 kHz    2 Hz SWR   Blank 486.6 us (43 km)

HOSR    24.65 MHz  -100.7 KHz  2Hz SWR   Blank 486.6 us (43 km)

SEAB     13.46 MHz  -49 KHz  2Hz SWR   Blank 668.8 us (60 km)  enhanced blanking is turned on.

The range on the SEAB site is low.
