Motivation

3

Higher Performance RADARs are needed for Autonomous Driving

Advanced requirements for Autonomous Driving:

► More warning time and 360° detection

More power on target, lower NF & phase noise

► High resolution & high unambiguity superior imaging

Many hits per target R,V, 𝜃, 𝜙

More detailed information of the scene and content

► Interference Mitigation

► Solution scalability to adopt to evolving requirements

► Highest levels of Functional Safety

This translates to high performance RADAR sensor requirements/challenges:

► +13dBm output power, over temperature

► Low phase noise (< -100dBc/Hz @ 1MHz)

► Low NF (<=13dB SSB)

► Broad FOV of antenna elements

► Fast chirps with high linearity supports high unambiguous velocity (10us / 1GHz)

Ultra fast settling (< 1us) supports fastest retrace time

4GHz chirp 3.75cm resolution

► Flexible waveform generation

Beam steering, phase coding, etc.

► Scalable for higher channel count

Phase & ADC synchronization

ADI’s

SpecsCustomer (Tier1/OEM) Value

High PA output

Power over Temp+13dBm

Longer detection range, targets seen sooner, better pedestrian

detection, reduced false detects

Superior Phase

Noise over Temp-100dBc/Hz@1MHz

Better detection of small objects (e.g. children) in presents of large

objects, targets seen sooner

Highest Modulation
