As the number of wireless broadband devices occupying our airwaves grows at a rapid rate, the resultant decrease in available spectrum for current technologies and increasingly stringent regulations on band compliance has necessitated adaptive RF technologies which can respond to the spectrum crisis. The task of maintaining the effectiveness of our RF technology with a shrinking spectrum has generated work in a number of fields, notably cognitive radar. This work focuses on developing an algorithm which can adaptively produce waveforms with desired accuracy in the range-Doppler domain, measured by the ambiguity function, for radar detection while also having characteristics which allow for efficient amplifier operation and spectral compliance.
