1. A radar detection system, comprising:

  • a set of four transducer means for receiving signals indicative of the location of an object;

    sorting means coupled to said set of transducer means for selecting the first, second and third strongest of said received signals and for generating therefrom first and second differential signals, said first differential signal corresponding to the difference between the strongest and second strongest of said received signals and said second differential signal corresponding to the difference between the second strongest and third strongest of said received signals;

    table means for storing at least one angular value corresponding to each of a predefined set of pairs of said two differential signals; and

    lookup means coupled to said sorting means and said table means for retrieving from said table means an angular value corresponding to the differential signal values generated by said sorting means.
