Slow-Time Coding for Mutual Interference Mitigation
Bo Tang, Wenjie Huang, Jian Li
Abstract
The mutual interference between similar radar systems can result in reduced radar sensitivity and increased false alarm rates. To address the interference mitigation problems in similar radar systems, we propose herein two slow-time coding schemes to modulate the pulses within a coherent processing interval (CPI). Specifically, the first coding scheme is designed through Doppler shifting and the second is devised via an optimization method. The proposed coding schemes are very easy to implement in practice and the incorporation of the coding schemes only requires slight modification of the existing systems. Our numerical examples indicate that the proposed coding schemes can reduce the interference power level in a desired area of the cross-ambiguity function significantly.
