SDR-EMB 2400AD4 is an advanced low-power and compact software-defined single-channel transmitter and four-channel receiver embedded radar unit in K-band. It is designed to support digital beamforming for applications in direction of arrival (DOA) measurement, radar interferometry, and digital beamforming. It is suitable for human activity monitoring, occupancy sensing, gesture sensing, and many other cases.
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
Typical output power of the transmitter is 18 dBm. Five 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 linearity of 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 FPGA-based processor module functions as a microcontroller, processor and power management unit, and offers ultimate design flexibility with industry-leading programmable logic. It has four 40-MSPS ADCs to support 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.
