Abstract : This invention relates to a data coder, code searching mechanism, data decoder, and range computer for a missile wherein the missile receiver is able to discriminate between the real signals and jamming signals. The system provides discrimination in aircraft receiver systems for the return synchronization signal. This is accomplished by utilizing a random code generator wherein the command data signals modulate the code train which in turn modulates the RF carrier. The missile contains a second code generator with a code searching mechanism which synchronizes the second code generator with the first generator. The comparison of the second code generator signal with the received signal produces the command signal as an output.
