A method for synthesis of antenna array layouts or selection of waveform in a set of mutually incoherent apertures for radar and radio-frequency applications

In a method for synthesis of antenna array layouts for radar and radio-frequency applications, the layouts are formed to comprise a given number of mutually incoherent apertures. For given space specifications for each aperture, number of transmit and receive antennas and field of views of the antennas, a design method is applied including: providing a metric with ambiguity functions based on a signal model that includes random initial phases between apertures, and selection of transmit and receive antenna locations according to said metric based on optimization of the ambiguity functions such that a sidelobe level and/or features dependent on the sidelobe level associated to said ambiguity functions over a number of dimensions corresponding to one or several parameters of interest, including azimuth and/or elevation, is minimized. A similar method is provided for selection of waveform, including frequency selection in stepped frequency waveforms, and pulse transmission times, for transmitters in a set of mutually incoherent apertures for radar and radio-frequency applications.
