摘要：
Signal synthesis using time-frequency distributions can be improved using an antenna array receiver. The availability of the source signals at different array elements allows the implementation of time-frequency synthesis techniques that utilize the source spatial signatures for crossterm reduction and noise mitigation. In this paper, we introduce a new technique for signal synthesis based on array averaging of Wigner distributions. The source temporal waveforms are first synthesized and then used to estimate the source spatial signatures. Iterative process incorporating the source signal vector and array vector can be applied until desired results are reached.
