An Adjusted Frequency-Domain Algorithm for Arc Array Bistatic SAR Data with One-Moving Transmitter [PDF]
Sensors, 2022 Arc array synthetic aperture radar (AA-SAR), which can observe the scene in all directions, breaks through the single view of traditional SAR. However, the concealment of AA-SAR is poor. To mitigate this, arc array bistatic SAR (AA-BiSAR) with the moving

The Synchronization Transceiver Design and Experimental Verification for the LuTan-1 SAR Satellite [PDF]
Sensors, 2020 The deviation between the two oscillators in BiSAR systems will cause a residual modulation of echo signal. Therefore, the phase synchronization is an important issue that must be addressed for BiSAR systems.

Electronics Letters, Volume 58, Issue 21, Page 807-809, October 2022., 2022 Abstract In mini‐unmanned aerial vehicle‐based high‐resolution bistatic synthetic aperture radar systems, the rotation of the unmanned aerial vehicle platforms will cause direct signal loss, resulting in the reduction of synchronization error compensation accuracy. Here, a synchronization algorithm is proposed to estimate the lost direct signal. First,
