Architecture for automation and fail operational automation

In an embodiment, an automation system for a vehicle may employ a variety of diversities to enhance reliability, accuracy, and stability in automating operation of the vehicle. For example, in an embodiment, an automation system for a vehicle may include multiple sensor pods with overlapping fields of view. Each sensor pod may include multiple different sensors in an embodiment, providing diverse views of the environment surrounding the vehicle. A set of sensor pods with overlapping fields of view may also transmit their object data at different points in time, providing diversity in time. Redundancy in other areas, such as the network switches which connect the sensor pods to an automation controller, may also aid in provided fail operational functionality. In an embodiment, the sensor pods may include local processing to process the data captured by the sensors into object identification.

Movement Compensation for Multi-Dimensional Radar Signal Processing
20230194705 · 2023-06-22 ·

This document describes techniques, apparatuses, and systems for movement compensation for multi-dimensional radar signal processing. A radar system receives radar signals reflected off of an object, and a two-dimension representation of the reflections is generated in the frequency domain. The two-dimensional representation illustrates attributes of the radar signals with respect to a fast-time dimension and a slow-time dimension. An energy peak within this two-dimensional representation is determined. Data associated with the energy peak, including a range and range rate, are determined from compensating the energy peak for movement of the object within a single frame. This compensation can include adjusting frequencies associated with the energy peak in the fast-time dimension and/or the slow-time dimension. The data associated with the energy peak is output to enable radar tracking with more accurate range and range rates measurements than can be output without performing movement compensation.

Radar Tracking With Greater Than Range Resolution Precision

To track an object with radar, and achieve greater than range resolution precision, the phase of a difference signal can be utilized and adjusted as the tracked object crosses between resolution ranges. Changes in the object's distance can be detected with greater than range resolution precision by utilizing the phase. Such changes can iteratively inform the determined distance across multiple phase cycles within a single distance range. As the movement of the object approaches, and then crosses, between resolution ranges, the phase as determined within an origin resolution range can be compared with a coincident phase within the destination resolution range and the difference can then be utilized to adjust the phase as the object then remains within the destination resolution range. Such phase adjustments can be applied across multiple resolution ranges, allowing for the tracking of an object, utilizing radar, while achieving greater than range resolution precision.
