I present an innovation approach to a RADAR technology without FPGA. Newer ARM microcontrollers and Linux systems have enough powerful computing that allows to gain access to fields of huge processing applications.This presentation is a practical of FMCW RADAR device implemented on standard ARM Cortex-A8 1GHz, SPI ADC and Linux.We have real-time constraints in FFT signal processing speed, so we use Linaro tools to generate better optimized code for ARM and NEON coprocessor.Moreover, we try to use hardware capabilities for parallel processing on DSP core, Linux driver with DMA support and threads.At last, we use HTML5 AJAX real-time data visualization. This way we reduce the payload needed in the embedded RADAR device. It moves that heavy task to remote HTML5 web browser. Presentation includes a brief walk through of the technologies used. It's a big step in terms of energy saving.
