(MHT) and Interacting Multiple Model (IMM) tracking algorithms (Blackman 2004) that are employed in the advanced avian radars we evaluated on the IVAR project. For the second part of the demonstration, Validation by Image Comparison, we compared screen images of the same targets that the radar operator would see using the analog BirdRad (or comparable) avian radar system with those the operator (or the detection and tracking software) would see using the digital eBirdRad system. We present those comparisons in Figure 6-39 through Figure 6-42. The images we used in this demonstration were captured at NAS Patuxent River, following the evening session on 17 April 2007, at approximately 23:48 UTC (19:48 EDT). The raw radar returns from the Furuno 2155BB radar at NASPR were split and fed both the BirdRad and eBirdRad simultaneously. Thus, both the analog BirdRad and digital eBirdRad systems processed the same data as input. In the figures below, the radar is located at the center of the display, the maximum range on both the BirdRad and eBirdRad units is set to 5.6 km (3.0 nmi), the range rings are either 0.9 km (0.5 nmi) (BirdRad) or 0.6 km (0.3 nmi) (eBirdRad) apart, and true north (000 degrees) is at the top of the display. 15 Results Validation by Simulation. The green circles in Figure 6-36 through Figure 6-38 indicate simulated bird detections; successive green circles represent the history of several radar scans and indicate bird movements from scan to scan. The brightest green circles represent the most recent location of the simulated targets, with a gradation to darker shades representing older or past scans. The red symbols represent the targets the DRP is automatically tracking: The red square at the center is the target’s most recent location, and the red line points in the direction the target is moving (i.e., its heading). The white numbers overlaying the red squares are the targets’ estimated speed in knots. The scale of the range markers is indicated on the horizontal axis, in nautical (1 nmi = 1.8 km) from the radar. The simulation time frame is on the order of 10 minutes from start to finish. In all scenarios illustrated in Figure 6-36 through Figure 6-38, the automatic tracking algorithms behave in a consistent and desirable manner when confronted with various target dynamics. Figure 6-36 shows the targets near the beginning of the simulation: There are four groups of separated targets, each group in a different quadrant and moving in different general directions. Approximately 3 minutes into the simulation (Figure 6-37) the targets have progressed so that the targets in the upper left quadrant are shown crossing, the targets in the lower left quadrant have continued in formation, the targets in the upper right quadrant have started to converge, and the targets in the lower right quadrant have made a sharp maneuver and begun diverging. Three minutes later (Figure 6-38), the targets in the upper left quadrant have completely crossed and separated, the targets in the lower left quadrant have continued in formation, the targets in the 15 Geographic north is 10º east of the north rhumb line in Figure 6-39 because the radar was not pointing to true north (which the display assumes), but was instead pointing 10º west of north. This cannot be corrected in the BirdRad system because it has no mechanism to rotate the image. In eBirdRad, on the other hand, the image can be rotated so that returns from strong reflectors are aligned properly with their position on the underlying georeferenced map. This in turn aligns the display to geographic north. In this way the eBirdRad display depicted in Figure 6-40 (and following figures) was rotated 10º counterclockwise so that geographic north is at 0°. 121
upper right have completely converged into a single track, and the targets in the lower right quadrant have been automatically deleted as they are no longer in the simulation. Figure 6-36. Near the beginning of the simulation, four groups of separated targets are shown. Detections (represented by green circles) as well as tracks (represented by red squares) are indicated above. The numbers represent the target's speed in knots (1 knot = ~1.8 km/hr). 122
