Radar target recognition by a logarithm bispectrum-based method

The paper starts with the definition of logarithm bispectrum and the presentation of its properties relative to target recognition. A relationship is established between the logarithm bispectrum feature of a target and that of the higher resolution range profile. As a result, the criterion for target recognition, based upon the relationship, is induced and its implementation is given. Simulation with some out-field acquired data is given to show that the approach is effective and advantageous over an existing one for rapid recognition.
