Radar target discrimination schemes using time-domain and frequency-domain methods for reduced data storage

Two correlative radar target discrimination schemes using the transient and spectral scattered-field responses are proposed. These schemes use time-domain and frequency-domain methods to reduce the amount of data that must be stored for each anticipated aspect angle. A discrimination range in degrees is used as a measure of discrimination performance. Experimental results show that the two methods require roughly same amount of storage space and an accurate discrimination is possible in adverse noise situations with signal-to-noise ratios (SNR'S) as low as -10 dB.
