Embedding communication symbols in radar clutter on an intrapulse basis
The concept of RCEC has been proposed, with the prospect of various different communication symbol and receive filter design strategies. Several of these symbol/filter designs were examined from the perspective of spectral containment, processing gain, probability of detection, and SER. Of the three proposed symbol designs, it was shown that the DP method of embedding communication symbols into clutter is the most effective from the perspectives of detectability, SER, and interference at the radar receiver. This symbol design offers significant improvements over a traditional DSSS design strategy. Finally, simulation results show that the DLDF provides the most robust performance for all symbol designs, independent of the incident clutter power.
