The Latics are currently bottom of the league and three points from safety after Saturday's 3-1 loss to Queens Park Rangers.
"Staying in the Premier League is like winning a trophy for us at Wigan and I believe we can do it again this season," Martinez said.
"The experience from previous seasons will help us.
"There's not much between the bottom five so, yes, it will be hard but I'm looking forward to it."
Wigan have won just two points from their last six games.
