Recent progress in radar imaging techniques enables high-resolution measurements of wind and turbulence by atmospheric radars. In order to implement radar imaging techniques to existing atmospheric radars, a cheap multi-channel receiver needs to be developed. Further, for improving and verifying radar imaging techniques, a digital receiver which can change its real-time signal processing is highly useful. We are now developing a low-cost configurable digital receiver. Because the digital receiver comprises a general-purpose software-defined radio receiver and a personal computer, its purchase cost is low and its real-time signal processing is easy to be implemented. In the presentation, we report the current development status of the digital receiver.
