The radar frequency spectrum is being dramatically affected by the commercial usage of wireless devices such as cell phones and wireless internet access. A new class of radar waveforms is needed in order to maintain the operational capabilities of radar and satisfy the interference requirements of neighboring commercial and military communication systems. The employment of orthogonal frequency techniques in radar systems offers an efficient use of channel bandwidth while optimizing the radar spectrum for, say, improving range resolution. The benefits of orthogonal frequency techniques to future radar designs show the potential of this technology in solving interference problems worldwide.
