Abstract
A method is provided for transmitting a plurality of narrowband signals in estimating a Doppler shift of a target object. The method includes simultaneously transmitting at least two narrowband signals from a source and receiving incident signals at a receiver. Multiple narrowband signals can be sent simultaneously and in combination with broadband signals from a source. The incident signals are filtered and processed to determine range and Doppler shift of the target.
