This paper considers the classification of radar targets using features extracted from the bispectrum of the backscattered signals. The classification performance of the bispectrum- derived features is compared with that of features extracted from the impulse response and the frequency response of the unknown target. In each case, the classification performance is evaluated using compact-range radar signal measurements of a set of five commercial aircraft. A number of scenarios of noise environment and azimuth ambiguity are considered. The case where extraneous scatterers are present in the vicinity of the measured target is also examined, and the effects of the extraneous scatterers are discussed.
