A121 Sparse IQ Service User Guide
User guide for the Acconeer A121 Sparse IQ Service, detailing API usage, sensor configuration, data retrieval, and memory management for pulsed coherent radar applications.
Overview
This document provides a comprehensive guide to the Sparse IQ Service used with the Acconeer A121 pulsed coherent radar sensor. It covers the Software Development Kit (SDK) architecture, including the RSS library, HAL integration, and sensor configuration. Key topics include system initialization, sensor calibration, data processing for complex IQ radar data, and power management through various idle states such as Deep Sleep, Sleep, and Ready. The guide also details advanced sensor control features such as continuous sweep mode, double buffering, and high-speed mode. Technical specifications for memory allocation in Flash and RAM are provided, along with a functional comparison between the A121 and the previous generation A111 sensor to assist in design migration.
Use Cases
- Implementing pulsed coherent radar data retrieval
- Configuring A121 sensor power states and sweep modes
- Developing radar applications for XM125 modules
- Migrating radar designs from A111 to A121 sensors
