It was only later that something came up hard and fast from behind, with the same tentative radar signature that they had seen before.

The radar signature has been reduced and its warhead can be changed depending on the mission.

By triangulating the radar signatures they know where we did it.

The images were clear; the computer, fooled at first, was learning the new radar signatures.

The design is said to have the advantages of greater pitch control and a smaller radar signature.

Japan and Israel are building sleek new ships with smaller radar signatures.

Don't want anything big or powerful enough to push our radar signature too high, now do we?

Hopefully, for it was not known at the time, various types of missiles would provide different radar signatures.
