Antenna Element Index Modulation for Frequency Diverse Array
Figure 9
Comparisons of MUSIC spectra of target 3 and target 4 for (a) square increasing frequency offset FDA with M = 16, ∆f = 3 kHz [18]; (b) cubic increasing frequency offset FDA with M = 16, ∆f = 3 kHz [18]; and (c) log-increasing frequency offset FDA (log-FDA) with M = 16, δ = 3 kHz [17].
