| Summary: | We present the matched illumination waveform
design for improved target detection in through-the-wall radar
imaging and sensing applications.We consider a multistatic radar
system for detection of stationary targets with known impulse
responses behind walls. The stationary and slowly moving nature
of typical indoor targets relaxes the orthogonality requirement
on the waveforms, thereby allowing sequential transmissions
from each transmitter with simultaneous reception at multiple receivers.
The generalization of the matched illumination waveform
design concept from a monostatic to a multistatic setting casts
the indoor radar sensing problem in terms of multiple-input multiple-
output (MIMO) operations and puts in context the offering
of MIMO to urban sensing and imaging of targets in enclosed
structures. Numerical electromagnetic modeling is used to provide
the impulse response of typical behind-the-wall stationary targets,
namely tables and humans, for different target orientations and
at various incident and reflection angles. Simulation results depict
an improvement in the signal-to-clutter-and-noise-ratio (SCNR)
at the output of the matched filter receiver for multistatic radar as
compared to monostatic operation. |
