Ej. Rothwell et al., A RADAR TARGET DISCRIMINATION SCHEME USING THE DISCRETE WAVELET TRANSFORM FOR REDUCED DATA-STORAGE, IEEE transactions on antennas and propagation, 42(7), 1994, pp. 1033-1037
A correlative radar target discrimination scheme using the transient s
cattered-field response is proposed. This scheme uses a one-dimensiona
l discrete wavelet transform on the temporal response to reduce the am
ount of data that must be stored for each anticipated aspect angle. Ex
perimental results show that a reduction in stored data of sixteen to
one still allows accurate discrimination in adverse noise situations w
ith signal-to-noise ratios as low as -5 dB.
