2029 Becker Dr Lawrence, KS 66047 Figure 2: US-D1 Cabling Interface 6. Installation Instructions Mounting Requirements: ● Radar face should be perpendicular to the target that to be measured ● Keep radar face clean, and do not cover it.
2029 Becker Dr Lawrence, KS 66047 Ensure altimeter will not be obstructed by mechanical landing gear! 7. Known Issues US-D1 is currently considered a ‘B-Sample’. Table 5 lists the known issues that will be addressed in future revisions.
2029 Becker Dr Lawrence, KS 66047 1 If US-D1 is used outside of its Maximum Operational Altitude(Table 1). Inconsistent small readings will be output(See Figure 4 below). ● For full confidence, only consider US-D1’s data when used within its operating range 2 Altitude data from US-D1 may have various step-size, since some post-processing algorithm is implemented after radar processing, e.g. averaging, filtering.
