Abstract

For the sake of the test and verification on Radar seekers of different projects in both infield and outfield, a digital wide-band noise jammer with flexible settings and adjustable parameters is devised. With FPGA and DDS dedicated chip as the core, the noise frequency modulation signal is generated, and the design of a programmable wide-band jammer is completed through pseudo-random sequence generation and DDS chip control. In addition to having high speed and high performance, the proposed design also has strong flexibility and reliability. Using MATLAB, Each step of the implementation progress is simulated and analyzed, and the feasibility of the scheme is verified.

Key words： noise frequency modulation; DDS; random sequence
