In this letter, a method based on jointly designing complementary sequences and receiving filters to suppress interrupted sampling repeater jamming (ISRJ) is proposed. The sequences and filters are optimized alternately using a gradient-based nonlinear programming solver and the Lagrange multiplier method. Numerical results demonstrate that the proposed method can generate sequences and receiving filters with good correlation properties and anti-ISRJ performance.
The realistic false targets caused by interrupted sampling repeater jamming (ISRJ) can mask the real target, leading to the failure of radar target detection. In this letter, a method based on jointly designing complementary sequences and receiving filters under the signal-to-noise ratio loss constraint is proposed to suppress ISRJ. A gradient-based nonlinear programming solver and the Lagrange multiplier method are used to optimize the sequences and filters alternately. Numerical results show that the proposed method can generate sequences and receiving filters with good correlation properties and anti-ISRJ performance.
