摘要
In digital radar systems such as orthogonal frequency-division multiplexing (OFDM) radars, high sampling rates are necessary to achieve high bandwidths and consequently a high range resolution. This constraint can be overcome by using an approach called frequency comb OFDM radar. In this proceeding, a hardware efficient implementation of such a frequency comb OFDM radar as well as a novel way of comb generation are presented. A universal method is developed to generate a frequency comb with arbitrarily selectable frequencies from a single source. This method is implemented in a circuit for a specific frequency comb. The functionality of the radar system using the developed comb generation scheme is demonstrated.
