Abstract:
An innovative highly-digitized radar system called GigaRad is currently under development by the DLR Microwaves and Radar Institute. An objective of the system is having a flexible, high-resolution imaging radar with wide-swath or 3-D capabilities, requiring transmission and reception on multiple channels simultaneously. However, a problem in multi-channel systems, especially in the transmit part, is the interference between simultaneously transmitted signals being operated at the identical frequency range. This paper examines the use of orthogonally coded waveforms as a method to overcome the interference between signals sharing the same bandwidth. First measurement results for a few selected waveforms are presented.
