Abstract
AbstractPulse compression processing of chirped signals can be treated as a matched filter reception process. However, generation of range side lobes is unavoidable. If a window function is used for suppression of these range side lobes, S/N loss occurs due to signal loss. Although it is possible to derive a window function realizing a desired characteristic such as side lobe‐free conditions by means of a convergence operation, it is not known whether the S/N loss is minimized because the requirement for S/N loss minimization is not taken into account. In the present paper, a method is presented for calculation of the window function and the pulse compression filter satisfying both the S/N loss minimum condition and the side lobe‐free condition. Simulation confirms that the derived pulse compression filter has a lower S/N loss than that in the method with a conventional window function and has a higher range resolution. © 2004 Wiley Periodicals, Inc.
