RFP Attachment 07 – CSDB Observations
FA7037-23-R-0002
The following is a consolidation of reporting for 1000 observations of the system over a several month period of time.
Summary: The system operates in X Band between 9367 and 9490 MHz. PRIs range from 300 to 2010 usec. Constant and Jitter PRI modes have been seen. Pulse duration ranges from 0.03 usec to 1.2 usec. Scan period ranges from 1.5 to 2.7 seconds. ERP ranged from 57.5 to 66 dBW.
Analysis Details:
RF: The majority of the observations fall within 9400 to 9420 MHz with no clear peak value.
PD / PRI: The majority of observations fall into three bands of values. Additionally a longer Pulse Duration was seen on two occasions. The PRI/PD modes follow:
Pulse Duration (usec) Constant PRI (usec) Jitter PRI (usec)
0.03 – 0.35 330-690 300-720
0.4 – 0.6 950-1050 920-1080
0.7 – 0.9 1650 – 1850 1620-1880
1.2 300 n/a
Scan: The overall scan period ranges from 1.5 to 2.7 seconds. There majority of the observations fall at 2.5 sec.
ERP: Only 15 observations provided ERP data. This data appears to fall into two ranges, supporting employment of both antennas seen in manufacturer brochures.
ERP (dBm) Lower Range Upper Range
87.5 93.2
88.7 93.5
88.9 93.7
89.2 93.8
89.3 94.0 -- 96.0 (88.7 dBm avg) (93.0 dBm avg)
