YJ-12 - YJ-12 ARM

YJ-12 ARM

The second family of YJ-12 is the anti-radar series and models in this family do not incorporate data links. The eventual goal is to develop an anti-radiation missile of AGM-88 HARM class, with a single passive radar seeker covering the entire frequency spectrum. Just as in YJ-91 ARM, a two step approach was adopted, with the first step being developing a series of seekers each covering a specific section of the frequency spectrum, so that they can be interchanged to meet specific threats. Meanwhile, a seeker that covers multi-bands frequency spectrum is under development for the future. A cheaper alternative is also developed, using GPS or other satellite navigational guidance, reducing the need of the costly VLSIC. The high capability VLSIC is needed during the flight of the anti-radar missile to calculate the approximate location of the target when the targeted radar is turned off after the missile is launched, but this would drive up the cost. GPS and other satellite navigational guidance would help the missile to remember the location of the targeted radar and continue the attack after the targeted radar is turned off, thus reducing the need of complex calculation. However, this cheaper version of guidance can only be used when attacking fixed site radar. Many Chinese sources have claimed that the fixed site radars built by Raytheon for Taiwan’s Surveillance Radar Program would be the primary targets of this satellite guided anti-radar version of YJ-12 ARM.
