1. A radar tracking system comprising:
- one or more processors; and
a data store coupled to the one or more processors having instructions stored thereon which, when executed by the one or more processors, causes the one or more processors to perform operations comprising;
receiving a radar return signal from an object;
determining whether radar return signal includes a transpositional modulation (TM) signal; and
identifying the radar return signal as a skin return signal or an electronic counter measure signal based on whether the radar return signal includes the TM signal.

Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting electronic counter measure (ECM) signals and embedding covert messages in radar or sonar signals. In one aspect, a method for detecting ECM signals includes receiving a radar return signal from an object. The method includes determining whether radar return signal includes a TM signal, and identifying the radar return signal as a skin return signal or an electronic counter measure signal based on whether the radar return signal includes the TM signal.
