A log–log plot of the average transmit power ﹩{P}_{A}^{T}﹩ and peak transmit power ﹩{P}_{P}^{T}﹩ vs. the total receive aperture effective area ﹩{N}^{S}{A}_{e}^{S}﹩ with fixed coverage (Ω_A = 10 arcsec²) corresponding to the swarm-probe case. The units are milliwatts for average power and kilowatts for peak power, so there is a six-order-of-magnitude difference between the two curves. The filled circles represent the nominal case for the parameters listed in Tables 1–4. The larger powers to the left of the filled circles reflect a larger choice for SBR, culminating with the SBR corresponding to a single aperture (N^S = 1). The smaller powers to the right of the filled circles reflect a smaller choice for BPP, culminating in BPP = 1, corresponding to a PPM frame with just two slots (M = 2).
