An iterative algorithm for the construction of notched chirp signals

This paper describes an iterative algorithm for the design of a constant-modulus finite-duration chirp-like signal having a notch in its frequency spectrum. Frequency-notched signals with good pulse compression properties are needed in wide-band radar systems that must avoid radiating into frequency bands assigned to other systems (e.g. communication and navigation systems). The algorithm is computationally efficient and provides explicit control of the notch frequency and notch order.
