An adaptive leakage signal canceller for a CW radar
Adaptive signal cancellation has been a topic of interest in many applications such as preventing radar jamming and cancelling noise and distortion in amplifiers. This work focuses on using adaptive signal cancellation to cancel the direct path signal straight from a transmitting antenna to a receiving antenna in a radar system. The theory, simulation, and design of a 2.4GHz cancellation scheme are presented, and it is shown that 45.84dB of attenuation is possible. The design is based on analog components, which sets it apart from many systems based on digital signal processors. System issues that limit the possible attenuation are discussed, and possible future work based on this project is also presented.
