摘要：
Multinode transceiver division systems can cooperate across multiple domains, including space, time, frequency, and energy, through waveforms. Moreover, it can provide greater anti-interference degrees of freedom than that from a single radar. Through this paper, we propose a frequency domain cooperative waveform design method based on two short baseline transceiver separation systems to resist multi-mainlobe interference. First, a narrowband detection signal with a locally good autocorrelation level was optimized using the Majorization-Minimization-based Proximal Method of Multipliers (MM-PMM) algorithm. Then, according to the characteristics of the frequency hopping of the narrowband detection signal, the corresponding wideband signal with a null spectrum was optimized as the cover signal of a narrowband signal. Further, two transmitting nodes were used to transmit the narrowband and wideband signals. Finally, a signal processing method based on phase-coherent and nonphase-coherent joint accumulation, with known frequency agility was used to process © 2022 Institute of Electronics Chinese Academy of Sciences.
