The airborne communication and navigation (C&N) apparatus ATE system is the important apparatus for measure the working state and performance of the C&N automatically and quickly. It has explained the composition of the ATE system based on the virtual instrument, the bus structure and signal recuperated in this paper. The ATE System adopts(More)
For the estimation of 4-D parameters (carrier frequency, azimuth, range, and polarization) in near-field narrowband sources, a new method based on fourth-order cumulant was presented, which used a polarization sensitive array and the multiple-rotational invariance to estimate 4-D parameters of sources. Without spectral peak searching or parameter pairing,(More)
