A Method that Can Observably Reduce the Multimode Interference Noise in the Signal of Interior Ballistic Measurement Radar

It is very weak that the reflected signal from the moving shell in gun tubes, due to the multi-mode interference noise. It is very important to eliminate the noise in order to improve the measurement accuracy. A method is presented which can eliminate effectively the noise by using the whitening method and K-L transformation. The mathematical derivation and the program which is designed with Labview8.0 prove the method is correct and effective.
