After reacquiring a lost target, what should you verify to ensure data integrity?

The main idea here is to keep the measurement framework consistent so you can trust the target data. After reacquiring a lost target, verify that the radar range scale is unchanged because the numeric range and related track data depend on that scale. If the scale were altered, the same on-screen position could correspond to a different numeric distance, which would distort range, closure rate, and the sense of where the target actually is. Maintaining the same range scale keeps the target’s range readings directly comparable to prior measurements and preserves the integrity of the track.

Other factors like display color are cosmetic and don’t affect data integrity. Checking data against other sources is good practice for verification overall, but it isn’t the specific step that ensures the radar’s internal range data remain consistent. A wind report is not related to validating the radar reacquisition data.
