Efficient closed-form expressions for the point spread function are established for a forward-looking, ultra-wideband, near-field imaging algorithm that exploits a coherent frequency domain technique for focusing. The imaging performance resolution, sidelobe level, ambiguous artifact level, etc. is analyzed for on-surface and subsurface targets and compared for both single- and multi-aperture sensing geometries. The closed-form formulations and observations put forth herein are applicable for a standoff sensing system employing a two-end-transmitter bistatic configuration the theoretical results overall, however, can be readily extended for other standard sensing scenarios, including monostatic and fully multistatic ones.
