Cooperative Waveforms Design for Distributed Sites in Multiple Blanket Jamming

This article deals with the suppression of multiple mainlobe blanket jamming for a distributed system via an interesting cooperative waveform design strategy in the frequency domain. Specifically, we consider three sites including one transmitting/receiving site and two transmitting sites with a short baseline arrangement. We herein design a narrowband detecting signal with excellent autocorrelation for the transmitting/receiving site, and desired narrowband deceiving and wideband protecting signals for the other two sites. By doing so, a complex spectrum can be formed when the three signals arrive at the enemy jammers via reasonably controlling the powers and launch timings of the three sites. Thus, the enemy jammers cannot identify the detecting signal, resulting in degradation of the jamming efficiency. Numerical simulations are conducted to assess the performance of the proposed strategy compared with the classic distributed multiple-input multiple-output (MIMO) mode and single-input single-output (SISO) mode in terms of multiple blanket jamming.
