Abstract
Bat biosonar offers a natural source for biomimetic design of radar waveforms with inspirations falling into two categories: (1) biosonar principles similar to ones already employed in radar and (2) principles used by bats that operate in ways not yet understood or not yet embraced yet for radar. This second type offers the possibility for driving radar innovation. Hyperbolic frequency modulation (HFM) waveforms were one of the first aspects of bat biosonar to catch the attention of the radar community. Relative to the popular linear frequency modulation (LFM) waveform, HFM is less vulnerable to Doppler shifts from targets' relative velocities. Another promising possibility for biomimetics is the remarkable ability of some bats to resolve closely-spaced objects using acoustic frequencies on a small platform. Bats' ability to operate in swarms is of interest to radar designers concerned about mutual interference between ships or planes using the same waveforms and frequencies. As bat researchers approach an understanding of the mechanisms behind these, and other, abilities of bats, their results will find a ready audience. This talk will discuss aspects of bat biosonar offering payoffs for radar design, including but not limited to improved resolution, Doppler tolerance and mitigation of inter-system interference.Bat biosonar offers a natural source for biomimetic design of radar waveforms with inspirations falling into two categories: (1) biosonar principles similar to ones already employed in radar and (2) principles used by bats that operate in ways not yet understood or not yet embraced yet for radar.
