Russian Su-34 Strike-Fighter Seen Covered in Tires

"A covering of tires could well be calculated to break up the infrared signature of these aircraft, to confuse cruise missiles using image matching for targeting. This technique is also frequently referred to as DSMAC (Digital Scene Matching Area Correlator) or ATR (Automated Target Recognition) when used in cruise missiles. As we have previously discussed, using DSMAC/ATR would provide land attack versions of Ukraine’s homegrown Neptune missiles with a significant advantage, making them largely immune to electronic warfare jamming. At the same time, their approach to the target would not involve any telltale radio-frequency emissions, thanks to the passive nature of the targeting."
