Martin has been called up to Gordon Strachan's squad for their upcoming Euro 2016 qualifiers, and he is hoping to make a starting appearance for his country in their next two games.
However, the 26-year-old insists that his main aim is to continue playing well for Derby, where the expectation is on him to fire them to promotion.
"There are some good players in that squad and I've had to bide my time and wait for an opportunity [with Scotland]," Martin said in the Derby Telegraph.
"I had a little one against England and didn't take it, really, so I've got to build my way up.
"The only way I'm going to get back into that squad is by doing well for Derby and my main focus is on that."
Martin has seen the competition for places at the Rams increase this season, with Paul Clement bolstering their forward line over the summer.
So far he has been able to fend off all challengers though, and he has scored five goals in his first 12 appearances so far this season.
That backs up the impressive campaign that he had last term, where he netted 21 times, as Derby just fell short in the promotion race.
Martin is yet to score for Scotland in six appearances, but one of his country's upcoming games is against Gilbraltar, so he will have a good opportunity to open his account, should he get the chance to play.
