چکیده
In this work, we consider a radar system where the antenna elements are arbitrarily distributed in space with several hundred wavelengths away. We call such a radar system distributed aperture radar system. We assume that the system is operating in multi-pathing environment, such as an urban area. We present methods for designing clutter rejecting waveforms and for reconstruction of reflectivity function. This work generalizes the monostatic radar waveform design method for range-Doppler imaging developed in [1, 2] to distributed aperture radar systems. Our approach utilizes GramSchmidt orthogonalization (GSO) procedure. The designed waveforms also lead to a filtered-backprojection type reconstruction of the reflectivity function which can be efficiently implemented in a parallel fashion.

متن کاملCMA beamforming for multipath correlated sources
Blind adaptive beamforming is often used in communication systems to combat co-channel interference. Among a number of techniques, the constant modulus algorithm (CMA) has proven to be an e ective tool for blind beamforming of uncorrelated signals. Unfortunately, CMA beamformers encounter problems for correlated signals and interferences. In this paper, we consider correlated co-channel input s...
متن کاملDistributed Gram-Schmidt orthogonalization with simultaneous elements refinement
We present a novel distributed QR factorization algorithm for orthogonalizing a set of vectors in a decentralized wireless sensor network. The algorithm is based on the classical Gram-Schmidt orthogonalization with all projections and inner products reformulated in a recursive manner. In contrast to existing distributed orthogonalization algorithms, all elements of the resulting matrices Q and ...
