Methods We selected one paired dataset from MCASCP and SEA and three from NASWI for this demonstration. After measuring the amount of time it took the RFE to process a dataset with a 5-minutes or greater duration, we found that the fusion engine was running about 50 times faster than real time. To make the measurements we report more conservative and meaningful, we included in this section the fusion processing times from the more intensive computation intervals where fusion is actually taking place. The time intervals during which tracks from two radars are being fused varied in these studies from 1-13 minutes. Following the procedures outlined in Method 6, we loaded each dataset from the RDS to the RFE for processing. The RFE also includes a COP for visualizing the fused tracks. We used a TVW to playback recorded datasets so that the tracks from the individual radars could be examined and compared with those from the COP. The graphical results we present below are screen captures taken from the COP or the TVW. Results Beginning with the data from NASWI, consider the fusion COP illustrated in Figure 6-108. This image was generated from our first paired dataset collected at NASWI on 13 November 2009. 240
Figure 6-108: COP display showing fused tracks from the WIAR1 and eBirdRad radars at NAS Whidbey Island on 13 November 2009 at 01:55 UTC. Red tracks = WIAR1 radar; green tracks = eBirdRad radar. In this example we have circled the two separate targets of interest, which are offshore to the northwest. These fused tracks are characteristic of two distinct flocks of birds traveling in the same direction (approximately southwest), a small distance from each other. The fused tracks shown in Figure 6-108 were formed from track information from the two contributing radars: the WIAR1 tracks are displayed in red and the eBirdRad tracks are displayed in green. The WIAR1 is a 25 kW, X-band radar with a 6-foot array antenna (short pulse); the eBirdrad is a 50 kW X-band radar with a 4° dish antenna (short pulse). For the purposes of this demonstration, the antenna angle of the eBirdrad radar was pointed to 5° above the horizontal so its beam would overlap with the beam from the array antenna of the WIAR1 radar. The array antenna covers elevation angles from 0°-10°, while the dish covers 3°- 7°. The radars are located within 100 m of one other. The targets shown in Figure 6-108 first appeared on the radars at 01:54:33 UTC, and had ended by 01:56:31 UTC – an interval of 118 seconds. The RFE took only 2 seconds to process this 241
