摘要
A pulse diversity-based jammer cancellation processor is designed in this paper to cancel the deception electronic counter measures (ECM) signals repeated by a digital radio frequency memory (DRFM) for radar systems. In order to remove the conventional stationary hypotheses and the rigorous application conditions, an orthogonal transmission block code set is achieved in one pulse repetition interval by exploiting the orthogonal frequency division multiplexing (OFDM). The processor does not require parameter estimation and compensation across a period of a whole block code. It is applicable to rapidly varying conditions in the presence of deception jammers.
