Sparse Synthesis Aperture Imaging using Multistatic Coprime Scheme

摘要

In this paper, we propose a mmWave-based imaging method which applies multistatic radar and coprime measurements, to reduce the number of antenna and the amount of data. It replaces every monostatic radar by a pair of separated transmitter and receiver along with phase corrections. A plurality of receivers can simultaneously receive the reflection when a transmitter emits signals. Our proposal is testified by an equivalent experiment and the results indicate that the multistatic coprime measurement is implementable and can reduce the number of antenna to about 0.3% of the standard SAR (using half-wavelength measurements).
