The RFeye Array 300 Series from CRFS is an intermediate-sized spectrum monitoring and direction-finding system for vehicle-mounted deployment or fixed installations. The Array 300 uses a unique multi-layer approach that is more sophisticated and versatile than traditional direction finding. High-performance spiral directional antenna modules are optimized for different frequency bands and arranged in multiple orientations. The Array is sensitive to the majority of incoming signal polarizations including all linear polarizations, allowing reliable detection of signals including those invisible to most DF systems. It is available in three different receiver configurations either based on RFeye Node 100-8 with 100 MHz IBW and 8 GHz upper frequency, the Node 100-18 with 100 MHz IBW and 18 GHz upper frequency, or the Node 100-40 with 100 MHz IBW and 40 GHz upper frequency.
The RFeye Array 300 system includes timing and synchronization features which enable combined AOA, TDOA and POA techniques allowing all signal types in the range to be mapped, irrespective of signal power, bandwidth or frequency. They have a sweep speed of up to 390 GHz/s (at 2 MHz RBW), a sampling resolution of 16 bits per channel (I&Q) and a sampling rate of 125 MS/s. These systems include a 512 GB internal SSD (per node) and support external SSD via USB interfaces.
This DF and spectrum monitoring system is available in the weatherproof housing that measures 1.2 (Dia.) x 0.8 (H) m with N-type or SMA connectors. It supports Power-over-Ethernet (PoE) with a DC supply of 56 V and consumes 140 W of power.
