Aircraft X was making right closed traffic to Runway 7R. He disappeared from the scope somewhere near the crosswind to downwind turn then re-appeared on base. Aircraft Y did the same thing. This has been a problem for a long time. I have been at DAB for a long time and it has been a carryover in the log since before then. I've also been told our ASR-9 hasn't been optimized in 18+ years. We had a safety meeting not long ago and we came up with a plan of action to get this issue resolved and as far as I know; no steps have been taken to fix this particular safety problem. We've been having problems with FUSION since we got it and we have a Band-Aid on it for now but the RADAR coverage for the 7R/25L traffic pattern is still unacceptable. Fix our equipment whether the problem lies with our ASR-9 or STARS in general. This kind of presentation is UNACCEPTABLE AND DANGEROUS.
DAB Controller voiced concern regarding the on going lost target issue on the Tower RADAR when traffic is near crosswind to downwind; the reporter unsure if the problem resides in the ASR-9 and/or STARS equipment.
