Narrative:

Radar was being worked on--no targets showing/radar blocks (data tags). Only 1 of parallel runways closed to arrs (runway 13R). An medium large transport X had departed and not tagged up. Another medium large transport Y had landed and was rolling out on runway 13L. An small transport was #2 to land. While on the landline with dfw approach/departure control attempting to assist with untagged medium large transport X position approximately, the small transport announced that he was going around. I had no time to see it. My radar person was also my coordinator and had his own traffic to contend with. He could not pass on the handoff information. Staffing may have been a factor. Combined position yet another possibility. Constant repair work on or near runways make closures or partial closures quite normal here. Fri is usually our busiest time and day of the week. Airport personnel might consider doing 'fill in' work at another time, especially when it is between a taxiway and runway. It is sometimes confusing to understand a closure for something close to an active runway or taxiway. As usual, dfw arrival jams them in. This time there was no real problem. However, it seems that situations like this are increasing in frequency. I believe that they will continue to remain unrpted and uncorrected unless we all do something. The pilot of the small transport took corrective action and decided to go around. The lack of radar targets delayed the handoff procedure between dal and dfw (neither of us had raw radar). Distracted from the active runway, for just a few moments, but sometimes that is all it takes.

Title: ACFT FOLLOWING ANOTHER ACFT ON FINAL APCH GOT TOO CLOSE AND EXECUTED A MISSED APCH.

Narrative: RADAR WAS BEING WORKED ON--NO TARGETS SHOWING/RADAR BLOCKS (DATA TAGS). ONLY 1 OF PARALLEL RWYS CLOSED TO ARRS (RWY 13R). AN MLG X HAD DEPARTED AND NOT TAGGED UP. ANOTHER MLG Y HAD LANDED AND WAS ROLLING OUT ON RWY 13L. AN SMT WAS #2 TO LAND. WHILE ON THE LANDLINE WITH DFW APCH/DEP CTL ATTEMPTING TO ASSIST WITH UNTAGGED MLG X POS APPROX, THE SMT ANNOUNCED THAT HE WAS GOING AROUND. I HAD NO TIME TO SEE IT. MY RADAR PERSON WAS ALSO MY COORDINATOR AND HAD HIS OWN TFC TO CONTEND WITH. HE COULD NOT PASS ON THE HDOF INFO. STAFFING MAY HAVE BEEN A FACTOR. COMBINED POS YET ANOTHER POSSIBILITY. CONSTANT REPAIR WORK ON OR NEAR RWYS MAKE CLOSURES OR PARTIAL CLOSURES QUITE NORMAL HERE. FRI IS USUALLY OUR BUSIEST TIME AND DAY OF THE WK. ARPT PERSONNEL MIGHT CONSIDER DOING 'FILL IN' WORK AT ANOTHER TIME, ESPECIALLY WHEN IT IS BTWN A TXWY AND RWY. IT IS SOMETIMES CONFUSING TO UNDERSTAND A CLOSURE FOR SOMETHING CLOSE TO AN ACTIVE RWY OR TXWY. AS USUAL, DFW ARR JAMS THEM IN. THIS TIME THERE WAS NO REAL PROB. HOWEVER, IT SEEMS THAT SITUATIONS LIKE THIS ARE INCREASING IN FREQ. I BELIEVE THAT THEY WILL CONTINUE TO REMAIN UNRPTED AND UNCORRECTED UNLESS WE ALL DO SOMETHING. THE PLT OF THE SMT TOOK CORRECTIVE ACTION AND DECIDED TO GO AROUND. THE LACK OF RADAR TARGETS DELAYED THE HDOF PROC BTWN DAL AND DFW (NEITHER OF US HAD RAW RADAR). DISTRACTED FROM THE ACTIVE RWY, FOR JUST A FEW MOMENTS, BUT SOMETIMES THAT IS ALL IT TAKES.
