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 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. Application Notes Table 5 lists the application notes that will be addressed in future revisions. Table 5: US-D1 Application Note Issue ID Description 1 If US-D1 is used outside of its Maximum Operational Altitude(Table 1). Inconsistent small readings will be output(See Figure 4 below).
2029 Becker Dr Lawrence, KS 66047 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. ● No action needed 3 Altitude data from US-D1 may give unexpected or incorrect measurements under operation in an indoor environment. Multipath reflections of the sensor’s radio waves are complicated in enclosed environments and may therefore introduce errors in the radar’s processing.
