An effective method of active deception jamming for countering ISAR

To improve the efficiency of the jamming signal generation, a jamming signal generation method based on ISAR echo model is proposed. According to the jammer´s position as well as the false targets´ expected position, this method calculates the false targets´ every minimum resolution cell approximate delay time and its accurate phase compensation, then forms jamming pattern. While receiving the ISAR signal, the jammer can generate the jamming signal based on the jamming pattern and the ISAR signal. The simulation results demonstrate that the proposed method is effective and feasible.
