EFFICIENT RADAR TARGET RECOGNITION USING A COMBINATION OF RANGE PROFILE AND TIME-FREQUENCY ANALYSIS

By S.-K. Han, H.-T. Kim, S.-H. Park, and K.-T. Kim

Abstract:
In this paper, a new hybrid classification method using both range profile (RP) and time-frequency image is proposed. The time-frequency image is obtained using the short-time Fourier transform before calculating the RP and this image is used for classification. 2-Dimensional Principal Components Analysis (2DPCA) is used to further compress the time-frequency image and to derive useful features from the image. The proposed method achieves a higher correct classification ratio than existing methods, especially when the signal-to-noise ratio is low.
