  1. With the established rf front - end system simulation platform, adding the digital modulated baseband signal, this paper simulated the multifold digital modulated signal ’ s transmission, such as 2ask, qpsk, and 16qam. then researches of power compression and phase noise of local oscillation influence the bit error ratio for different modulated system. the designing is satisfied multifold functions request with the high - powered and integrated broadband rf front - end

    隨后在建立的寬帶射頻前端通用模擬平臺上，加入基帶數字調制信號，對多種數字調制格式的信號在該通用平臺上的傳輸作了研究，模擬了2ask 、 qpsk和16qam等調制格式信號的發射與接收，研究了功率壓縮和本振相位噪聲對不同調制的誤碼率影響，實現了滿足多種功能要求的寬帶高性能綜合射頻前端的設計。
  2. Give some simulation result about noise cancelling, find the optimal delay, then estimation of doa with the narrowband signal and broadband signal at different snr. the results show that the method is feasible

    對本艦噪聲抵消過程進行了模擬，首先確定最佳延遲，然後在抵消的基礎上分別對窄帶和寬帶目標信號進行方位估計，驗證了該方法的正確性。
  3. In the broadband incoherent beamspace high resolution method, the outputs of mvdr beamformers are used to suppress the interference from outside the beam coverage region in each subband. computer simulation results show good performance at low signal to noise ratio ( snr )

    該方法克服了基於預成恆定束寬波束輸出的寬帶相干高分辨處理方法不能有效抑制波束區域之外強于擾的不足，模擬結果表明該方法在低信噪比具有良好的性能c
