reported DGFT mode - TMS up to reacquire new target puts radar into full azimuth scan instead of looking boresight or following the JHMCS

[darkman222]

Reproduction:

DGFT switch to DGFT

TMS up (activate Radar)

TMS up (activate JHMCS)

Look at target ( auto lock)

Look away from target

TMS up ( to reacquire new target)

Look around, radar elevation follows as intended, radar azimuth scans the full radar azimuth.

 

Expected:

TMS up should slave the radar to the JHMCS in elevation and azimuth. Not in elevation only.

 

Plausibility:

See at the end of the video while looking right, target on the left gets locked. Seems not to work as intended or practical in a dogfight.

 

If further doubts exist, I am sure it behaves the same without the JHMCS with normal ACM radar boresight modes. Will add that later.

EDIT:

*******

Same for DGFT Boresight mode.

Elevation stays in boresight center, azimuth scans full azimuth range if going TMS up with a locked target and if not being cancelled by a TMS down before.

Bump, because it was tagged while I was editing. See edit above for behavior in ACM Boresight too.

Hi @darkman222

Thank you for bringing this up, this was reported internally for analysis.
