Introduction

The primary aim of the BTID is to positively identify friendly forces on the battlefield in order to reduce fratricide and maintain or improve combat effectiveness. To achieve this aim designated platforms on the battlefield will be fitted with some or part of the NATO BRID. This NATO BRID is a millimetric wave question and answer system working in the Ka band. It comprises two main components, an interrogator, which allows a platform to question another platform with an encrypted message, and a transponder, which decodes the message and replies with an encrypted answer. Transponders will be fitted to all designated platforms, while interrogators will be fitted to only those designated platforms with an offensive or reconnaissance capability.

This STANAG is intended to define the design criteria for a common waveform, and any necessary performance requirements, for an interoperable BTID. The waveform also supports some non-mandatory capabilities, which can be implemented by individual nations should they be required.
