BAE Systems Australia's Direct Digital Receiver (DDRx) is designed to support the demanding High Frequency (HF) radar application, which requires the detection and processing of minute energy returns in the presence of large inter-continental broadcast signals.
The receiver was collaboratively developed with scientists and engineers from Australia's Defence Science Technology Organisation (DSTO). The receiver is housed in a half-width, one rack unit high case. The receiver is available in two configurations.
The first supports output of eight concurrent narrowband channels, at limited dynamic range, while the second configuration provides a single concurrent wideband, with two narrowband configurations and an astounding dynamic range. Both configurations employ analogue filtering to allow pre-conditioning of he signal prior to the A/D converter.
