Abstract

The application of the linear frequency diverse array (LFDA) provides the more freedom for the waveform design in time, frequency, amplitude and phase domain. The antenna pattern of the LFDA is analyzed firstly. The main-lobe width of the antenna pattern is narrower and narrower with the increasing of the frequency interval between antenna elements. The ambiguity function of both LFDA and the conventional broadband linear frequency modulation (LFM) signals is compared. The blur between range and Doppler of the LFDA ambiguity function is improved evidently. The simulation and assay indicate that the application foreground of the LFDA is comprehensive.
