SDR-EMB 240AD is one-transmitter and one-receiver embedded radar unit in S-band. Its center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 2.25-2.6 GHz. Its typical output power of the transmitter is 22 dBm. The maximum detectable range is about 200-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
It is designed to support human activity monitoring, vital-sign detection, gesture sensing, through-the-wall, and many other indoor and outdoor target detection and imaging.
The RF Module is implemented with phase-locked loop (PLL) to achieve linearity in frequency modulations. The center frequency and the bandwidth of transmitted signals are selectable and adjustable within a wide frequency band of 1.95-2.55 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 two 40-MSPS ADCs to support the receiving channel. 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.
