Radar System and Method for Operating a Radar System

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a radar system that employs multiple transmit-receive units (each with its own antennas and radio frequency (RF) generator) synchronized by a common clock. The core idea is to process the signals from these units to improve their coherence, which leads to more accurate and higher resolution radar measurements. Advanced signal processing compensates for synchronization errors and phase noise between the channels, enabling better distinction and measurement of targets, even in challenging conditions.

Use CasesContent extracted from patent full text and abstract with AI.

• Automotive radar for advanced driver-assistance systems (ADAS) and autonomous vehicles
• Industrial process monitoring and automation (e.g., object detection and localization in manufacturing)
• Security and surveillance systems requiring precise motion and position detection
• Aerospace and aviation radar applications for improved target tracking and resolution
• Medical imaging and non-contact vital sign monitoring using radar sensing
• Environmental monitoring such as traffic counting, weather sensing, or wildlife tracking

BenefitsContent extracted from patent full text and abstract with AI.

• Improved angular and spatial resolution in radar measurements, allowing more precise target separation
• Higher measurement accuracy due to increased signal coherence across multiple transmit-receive channels
• Enhanced ability to detect weaker targets near strong reflectors, improving sensitivity and dynamic range
• Reduced influence of phase noise and hardware synchronization errors, leading to more reliable operation
• Simplified hardware layout by allowing partially integrated, distributed radar transceivers
• Compatibility with modern integrated circuit radar chips and systems with multiple antennas
• Reduced computational requirements in post-processing thanks to linear, coherent signal combination

Patent Abstract

The invention relates to a radar system comprising: - at least a first (SE1) and a second (SE2) transmitting-receiving device with in each case at least one transmitting antenna and at least one receiving antenna as well as a HF generator, and - a common clock generator for the HF generators of the transmitting-receiving devices, wherein at least one evaluation device is provided, which is configured to process transmitting and receiving signals of the transmitting-receiving devices (SE1, SE2) to modified measurement signals with increased coherence.
