SDR-EMB 2400T2R4 is two-channel transmitter and four-channel receiver embedded radar unit in K-band. Its center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 24-26 GHz. The signals are transmitted in a time division multiplexing manner.The maximum detectable range is about 42-m for 1-sm of RCS.
Embedded unit features include:
- Embedded Linux OS
- Custom-designed battery management system – up to 4 hours on a single charge
- 7-inch touch-screen display
- Remotely controllable– suitable for field trials
The 2400T2R4 is designed to support digital beamforming and MIMO capabilities for applications in direction of arrival (DOA) measurement, radar interferometry, digital beamforming and MIMO phased-array radar. It is suitable for human activity monitoring, occupancy sensing, gesture sensing, and tracking of 3-D trajectory.
Typical output power of the transmitter is 22 dBm. Six single-ended SMA female connectors are installed for easy connection to external antenna units.
The RF module is implemented with phase-locked loop (PLL) to achieve great linearity in frequency modulations. The center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 24-26 GHz. The signals are transmitted in a time division multiplexing manner.
The FPGA-based processor module functions as a micro controller, processor and power management unit and offers ultimate design flexibility with industry-leading programmable logic. It has four 40-MSPS ADCs to support the four receiving channels. A high-speed USB peripheral controller enables digitized raw data streaming to a memory storage for post-processing. It interfaces with the RF Module with a 24-pin flat flex cable (FFC) to form a standalone system.
Graphical User Interface
Built-in 7-inch touch-screen display with graphical user interface (GUI) allows the flexibility and adjustability in selecting desired signal waveform, center frequency, bandwidth, sampling rate, filtering, display parameters, and record/export I/Q data.
