Abstract

A new digital multichannel radio receiving system is described. The system was originally designed as an adaptive-antenna receiver platform for antijamming purposes in the HF band. It consists of two main components: receiver hardware and antijamming software. The hardware design consists mainly of commercial off-the-shelf (COTS) components based on the VXIbus architecture. Antijamming algorithms are waveform-dependent and they are implemented in real-time digital signal processing software. The system can suppress unwanted interference and jamming signals with jamming-to-signal power ratios of up to 40 dB. This paper provides an overview of both the hardware and software designs. Specifications and performance of the system are also described
