Those are clearly supersonic ramp intakes. Looking at the tail of the thing, that is one wild hybrid. I don’t see a way to do pop out wings though, so that is confusing.
“The HF-3 missile uses a rocket-ramjet propulsion system, with two side-by-side solid-propellant jettisonable strap-on rocket boosters for initial acceleration and a liquid-fueled ramjet (believed to be using JP-10 fuel) for sustained supersonic cruise. The missile features a wingless design with four strake intakes and four clipped delta control surfaces aft. The air intake design arrangement was reported to have been optimized for evasive maneuvering at terminal sea-skimming altitudes. The missile is designed to be capable of way-pointing and can be programmed to fly offset attack axes to saturate defenses. It is also capable of high-G lateral terminal “random weaving” maneuvers to evade close-in defenses.”>
