Buy a clean, empty spray bottle, and some bottles of lemon juice. Spray copious amounts of lemon juice everywhere you don't want the cats to be. Most cats HATE citrus. The smell of anything citrus will usually drive them away, especially lemon.
Not always, though. Some cats are not bothered by it, for example, my uncle once had a cat that loved to eat Oranges.
It also depends on what is attracting the cats to your property in the first place. Are they coming to your trash cans for food garbage, or taking food you leave out for your dog or another pet?

If there's food or food garbage for them to eat, you will have to remove the food or seal up the garbage, or the lemon probably won't work very well.
