Abstract

In microwave remote sensing, chirp transform spectrometers (CTS) have not been widely used compared to other real-time spectrometers like acousto-optical-spectrometers (AOS) or digital autocorrelators (DAC). Recent progress in solid state physics and photolithographic processes has led to the availability of large time-bandwidth-product dispersive delay lines and high speed, low power digital electronics, which both is required to build a competitive CTS. A high resolution state-of-the-art CTS has been developed at our Institute. A functional description is given and its future development potential is discussed and compared with past and recent developments.
