早期f14那是個電戰系統alq-100,
後來加入了irst,但那是個垃圾並為完全採用
中期是個tcs 能紀錄影像的攝像頭
重點來了
AAS-42紅外線搜索暨追蹤系統(Infrared Search and Track, IRST)：提供紅外線影像及APG-71射控雷達數據，
那是90年代以後的事了而且f14d數量不多

給你這外行看一下這篇文章，順便幫你找關鍵字

Abstract
The radar has been indisputably the most important sensor in the battlefield, allowing early warning and tracking of air vehicles. Modern fighter ircraft employing AESA fire control radars are able to acquire and track targets at long ranges, in the order of 50 nautical miles or more. However, the proliferation of low observable or stealth technology has contested radar capabilities, reducing their detection / tracking ranges roughly to one third. This degradation is more severe concerning fighter aircraft radars, since most stealth threats are optimised for higher frequency bands, as in the case of fire control radars. Hence, other parts of the electromagnetic spectrum have been reconsidered, such as infrared radiation (IR). Every aircraft is a source of IR, due to fuel combustion, aerodynamic friction and IR reflection. In this way, a jet fighter can be detected by an IR sensor against the cold background of the sky. Therefore,IRST systems have re-emerged, offering an alternative to the radar. Apart from their capabilities concerning target detection (whether stealth or not), IRST systems also exhibit passive operation, resilience to jamming and better angular accuracy.
