Abstract :
A radar that transmits continuous band-limited random noise is considered. The target impulse response is constructed from the cross correlation of the received signal with the transmitted noise signal. The system uses a fixed-length delay line and relies on the target movement through the range gate. Range profiles of different automobiles are measured with this system and used in a target recognition example
