I don't think you can set a radius for the effect itself, just the radius that the damage is felt at.

You could use the explosion effect of a mine, like the Ripper, for the explosion of your missile. Or even the effect of a gas pocket exploding, or a mine, etc.

Try these:
explosion_nomad_mine (FX/effects_explosion.ini)
explosion_gas_mine (FX/effects_explosion.ini)

You could also use the effect from an exploding cap ship, though some of those may be way too big.

I've made a similar weapon, except it also disables cruise. The weapon is highly overpowered, so the explosion radius is so high that everyone in combat will loose their shield. I'm still waiting to confirm if the weapon drains a ships power, making it temporarily unable to fire its weapons.

Just a fore note, the IDS will need to be changed, because the ones I've used are custom ones. Items don't seem to show up unless you have an ID, so make sure you do that.

Anyway, heres the code I got.

This goes in weapon_good.ini

Finally, this weapon explodes almost instantly. An EMP launches a magnetic wave to disrupt power, so I don't believe it should have an effect. But if you're still not happy, I'd recommend using the Mine explosion, and adjusting the explosion radius accordingly.
