Auto-Scanning Quantized, Power Law Frequency Diverse Arrays

We extend earlier work with quantized-power-law, frequency diverse arrays by reincorporating linear frequency offsets. This provides a controllable scan pattern that is approximately linear over the range −45° to 45°. We give parametric design expressions for scan rate and peak-to-peak along-scan distance of the resultant FDA far field and present phase noise and frequency offset sensitivity analyses for a notional FDA that suggest uncertainty tolerances and scan range limits.
