Description - The Intelligence Advanced Research Projects Activity (IARPA) seeks information regarding innovative signal processing algorithms and sensing approaches used to characterize the D-region of the ionosphere (60–90 km). Currently, the D-region is chara cterized by remote sensing of very low frequency (VLF) signals and comparing that propagation with modeling results.[i]-[ii],[iii] However, this approach is highly nonlinear and fits the definition of an ill-posed problem in that itis quite difficult to solve and does not yield a unique one-to-one correspondence between electron density profiles in the Earth-ionosphere waveguide and signals at the receiver(s).  In the past decade, inversions of
