If you do only have HSM missiles then try not to down all the mig25's etc from the first wave. this way when the skies get full it will be much easier.
If you happen to have pricision missile or bomb then wait untill round 4-5 and ground targets will appear, the first survival map ensures they spawn tightly packed around the main bridge over the canyon, i couple of quick shots against these targets will get you this in no time.
