We have designed an experiment for low-cost indoor measurements of rank and other properties of direct and scattered signals with radar interference suppression in mind.
The signal rank is important also in many other applications, for example, DOA (Direction of Arrival) estimation, estimation of the number of and location of transmitters in electronic warfare, and increasing the capacity in wireless communications.
In real radar applications, such measurements can be very expensive, for example, involving airborne radars with array antennas.
We have performed the measurements in an anechoic chamber with several transmitters, a receiving array antenna, and a moving reflector.
Our experiment takes several aspects into account: transmitted signals with different correlation, decorrelation of the signals during the acquisition interval, covariance matrix estimation, noise eigenvalue spread, calibration, near-field compensation, scattering in a rough surface, and good control of the influencing factors.
With our measurements we have observed rank, DOA spectrum, and eigenpatterns of direct and scattered signals.
The agreement of our measured properties with theoretic and simulated results in the literature shows that our experiment is realistic and sound.
The detailed description of our experiment could serve as help for conducting other well-controlled experiments.
