Do you even know what is the purpose of CCD camera. You know what mmW guidence is meant for and how it is different from IIR?. Just donot know do you?.
Millimeter Guidence System:
Radar (active) guidance technology prevailed in anti-ship and surface attack weapons during the 1980s. This guidance technique was recently adapted to land attack missiles. After the missile flies to a pre-designated location where line of sight to the target is expected, it activates its radar in a scan mode, and will home in on the signal expected to be the target. Such signal can be the strongest in the area, or one that emits a characteristic signature. Radar guided missiles are highly vulnerable to countermeasures and deception, which sometime necessitate human intervention for target verification and intervention at terminal phase. When used over land, radar seekers can be augmented by other elements (such as EO, GPS, LADAR etc).
Other applications of much smaller radar guidance use millimeter wave radars, to locate, classify, identify and engage armored vehicles and other priority targets. The use of millimeter wave seekers provides very high resolution, all weather capability and high immunity to current conventional countermeasure techniques employed by armored vehicles.
Infrared Guidence System:
In a substantially non-spinning guided missile, a passive-infrared-imaging fuze comprising at least one set of body-fixed wide-angle optics providing at least forward hemisphere coverage, a multi-element detector array and a microprocessor for image and data processing, aim-point selection and fuzing;
Infrared homing refers to a passive missile guidance system which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles which use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and retain heat, and as such, are especially visible in the infra-red wavelengths of light compared to objects in the background.
Now you know what you are talking about...........
