DATA TAG JUMP TO FALSE TARGETS INDICATED ACR X HAD LTSS FROM ACR Y. EDP ALARM. SITUATION: FALSE TARGETS BTWN THE ALEXANDER RADAR SITE AND 25 MI.

Narrative

THE AREA AROUND THE ALEXANDER RADAR SITE HAS BECOME NEARLY IMPOSSIBLE TO WORK DUE TO POOR RADAR DATA PROCESSING CAUSING NUMEROUS FALSE TARGETS AND LOSS OF TARGETS. ACR X AND ACR Y WERE ESTABLISHED 12-14 NM IN TRAIL PRIOR TO AND AFTER XING OVER THE AREA YET THE ROP INDICATED LESS THAN 5 NM AT ONE TIME BECAUSE THE TRACK 'TAGGED UP' ON A SERIES OF FALSE TARGETS. IN THE PAST; THE SORT BOXES WERE STRATIFIED IN THIS AREA TO TRY TO ELIMINATE MOST OF THE PROBLEM; BUT 3-4 MONTHS AGO THE SYS ENGINEER DECIDED WE DIDN'T NEED THIS 'PATCH' ANYMORE AND REMOVED IT FROM THE PROCESSING. SINCE THEN WE HAVE DOCUMENTED THE TARGET PROBLEM WITHOUT ANY RESPONSE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. THE RPTR STATED THE INCIDENT WAS INVESTIGATED AS A SYS ERROR. THIS REVEALED THE RADAR PROBLEM WITH FALSE TARGETS. THE SYS ENGINEER HAD REMOVED A PATCH BECAUSE OF COMPLETE LOSS OF TARGETS TO RING THE ALEXANDER RADAR ANTENNA SITE. THIS PROBLEM IS ONGOING. THE RPTR STATED HE WAS TOLD THE PATCH HAS BEEN REINSTALLED AS OF THIS DATE. PROBLEM STILL PERSISTS. RPTR STATED IF PROBLEM NOT SOLVED HE WILL FILE A UCR.
