A multifunctional broadband receiver for bistatic X-band radar measurements

This paper presents the multifunctional use of a developed dual-channel broadband receiver for bistatic radar applications. Modern broadband receivers integrate more and more functionality due to their increased performance. For example, the simultaneous operation of radar, communication applications and spectrum sensing is possible with a single receiver. Broadband antenna elements, radio frequency stages and corresponding analog-to-digital converters enable the multifunctional use over a wide frequency range. This reduces the overall hardware costs as the required tasks can be performed with the same device. In this paper we therefore demonstrate the multifunctional use of the receiver also for bistatic radar applications using a X-band radar as cooperative illuminator. A signal processing methodology using the sampled data from a reference and surveillance channel and the known transmit pulse parameters is presented to perform range-Doppler processing. The performance of the proposed approach is demonstrated with measurement data collected during several measurement campaigns in different rural terrain types representing the probable environment of operation for such a receiver.
