Design of Multi-Mode Microwave Control Combination for InSAR System

Article Preview

Abstract:

This paper provides a multi-mode Microwave Control Combination (MCC) for InSAR system, where the center frequency is F0 with 800 MHz bandwidth, and the size is smaller than 355mm×480mm×155mm. A special InSAR system is introduced with finite baseline between antennas, gets the equal baseline longer by the way of MCC fast switch and makes the channel phrase satisfy the special InSAR system demand. In the MCC design, isolation between antenna channels, high-power and fast channel switch of the system are considered firstly, which are very important in finite airborne space for this InSAR system. The combination system can be changed to three working modes with different configuration but same external interface. This MCC can support average power 400w and peak power 4000w, achieve isolation between radiation channels more than 48dB and channel switch time less than 10μs.
