[0016] Overview

[0017] This document describes the techniques and devices to achieve radar attenuation suppression. These techniques and devices are designed to improve radar performance by suppressing the attenuation and distortion effects of the attenuator by determining the characteristics of the attenuator or the properties of the radar signal.

[0018] Generally, a radar system includes a radome or some form of housing composed of radio frequency transparent materials. The radome minimizes the attenuation of radar signals passing through the radome while protecting the radar antenna from weather and debris. Although electronic devices can have external housings or protective housings that can protect embedded radar systems, these housings are generally not designed for radar applications. In some cases, these enclosures are made of materials that attenuate or distort the radar signal, thereby reducing the effective range and accuracy of the radar system.

Abstract

Techniques and apparatuses are described that enable radar attenuation mitigation. To improve radar performance, characteristics of an attenuator and / or properties of a radar signal are determined toreduce attenuation of the radar signal due to the attenuator and enable a radar system to detect a target located on an opposite side of the attenuator. These techniques are beneficial in situations in which the attenuator is unavoidably located between the radar system and a target, either due to integration within other electronic devices or due to an operating environment. These techniques savepower and cost by reducing the attenuation without increasing transmit power or changing material properties of the attenuator.

Description

Background technique [0001] Radar is a useful device that can detect and track objects, map surfaces, and display weather patterns. Although radar is a common tool used in military and air traffic control operations, technological advances are making it possible to integrate radar in electronic devices. In many cases, radar can replace bulky and expensive sensors (such as cameras) and provide improved performance in the presence of different environmental conditions (such as low lighting, motion, or overlapping targets). Although the use of radar may be advantageous, there are many challenges associated with the use of radar in commercial devices and commercial applications. [0002] One such problem involves integrating and operating radar in the presence of attenuators. The attenuator may include the outer casing of the electronic device or another outer material that attenuates or distorts the radar signal. Because the available power may be limited in small and mobile radar...
