MIMO STAP clutter mitigation performance demonstration using acoustic arrays


Journal Article

This paper demonstrates MIMO STAP radar techniques for Doppler-spread clutter mitigation using a 5-element transmit speaker array and a 16-element receive microphone array. Doppler-spread clutter is mitigated by "virtual" transmit beampattern nulling using partially-adaptive beamspace slowtime MIMO STAP (SLO-MO) on received audio data. For a transmit beamspace dimension of three, the ability of SLO-MO processing to achieve a 30 dB suppression of Doppler-spread clutter using only a single adaptive transmit degree of freedom is demonstrated. Additionally, MIMO acoustic array processing is shown to be useful in understanding factors which impact radar performance like clutter spatial spread. © 2008 IEEE.
