Narrative:

Two pilot training mission was launched out of ZZZ1-ZZZ2 in aircraft X then direct to ZZZ. The winds at ZZZ 010 @ 7 kts. We decided to land runway xx and enter right traffic as published. On approach; we did not see any other aircraft on TCAS. We made radio calls starting at 5NM west; to join midfield downwind after crossing midfield. We made additional radio calls with no response on the overhead; downwind; base; and final for runway xx. Upon turning final; we noticed nothing abnormal and continued the final decent. We entered the flare and during the flare; saw a landing light approaching on the centerline opposite direction on runway yy. We immediately began a go-around and offset to the east of the centerline and climbed out to rejoin the pattern missing the other aircraft by roughly 100 feet. Aircraft Y; that was on the runway did not make any known radio calls or take evasive action.additionally; at no point did we get a TCAS warning from our system.after landing; we made contact with the other pilot who explained he had the frequency input incorrectly into his radio and claimed to have been making calls without response.aircraft Y's lack of calls and long straight in approach over the lake instead of flying the pattern made them hard for us to spot.
