heat signature

Our position on the map is indicated by heat signature .

我们在地图上的位置由热感应点标出。

Infrared 's having a hard time picking up a heat signature . sand 's too hot .

热能追踪器很难追踪到目标。沙子太热了。

If the IRCM ( infrared radiation countermeasure ) isn 't on the same wavelength as the incoming , it will have the opposite effect , increasing the aircraft 's heat signature , rather than masking it .

如果IRCM（红外热辐射干扰系统）不是按照进袭同样的波长，它会有相反的效果：增加飞机的热信号，而不是掩蔽它。
