Target Simulation & Signal Analysis for Automotive Radar
Exceptional Performance at an Affordable Price
The Challenge
The installation of collision warning and Adaptive Cruise Control (ACC) systems on passenger automobiles and long-haul trucks
challenges manufacturers of vehicles and radar modules alike. Integrating a sensitive radar module and its associated antenna into
a vehicle platform is not an easily predictable task. The introduction of new technologies like millimeter-wave radar testing into your production facility, coupled with the requirement to drive costs as low as possible, puts heavy demands on your design engineers, test department and your entire production team.
Developing test procedures that are comprehensive in terms of functionality and accuracy but are fast and easy to initiate requires
care and forethought. Guaranteeing performance and reliability in high volume manufacturing is always difficult. Finally, drive-by
testing after installation is time-consuming and lacks accuracy and repeatability. These factors make it essential to test to a known
set of parameters using a quality instrument of verifiable accuracy and repeatability.
The Solution
Whether you are a designer of radar systems or a manufacturer of passenger automobiles, long-haul trucks, radar transponders or
antennas, you need to maintain your reputation for quality and safety. As ACC technologies mature, as customers realize the
benefits of using these systems and as production volume soars, new testing technologies will be required to keep your
manufacturing competitive and to maximize profitability.
At Keycom we understand that testing millimeter-wave radar within the confines of a high-volume vehicle production line will be a
new experience for many automotive engineers.We also understand the importance of performance verification testing to ensure
quality. By bringing our experience in radio frequency, microwave and optical testing to bear on your requirements, Keycom can
deliver test capability that keeps you ahead of the competition. The ME7220A Radar Test System accurately and repeatedly
characterizes ACC radar modules to ensure quality and optimum functionality.

ME7220A Radar Test System (RTS)
The Ideal Solution for Your Testing Environment …
Research and Development:
| Verifies operation under realistic conditions by simulating moving targets (other vehicles or roadside objects) at multiple target distances |
| Fully characterizes the radar module by quantifying transmitter, receiver and antenna performance |
| Integrated functionality allows radar signal power and frequency measurements without external equipment |
| Suited for stand-alone bench-top testing, but easily integrates with other instruments into a test bench or rack |
| Built-in laser allows accurate alignment of the radar-under-test to the RTS antennas without additional mechanical fixtures |
Radar Module Manufacturing:
| Integrates into standard production lines or automated radar test stations for complete testing of the radar modules |
| Allows full or sample testing of all critical radar parameters accurately and repeatedly in a confined and controlled environment |
| Ideal for anechoic chamber testing of radar components and modules |
| Interfaces with external test accessories including spectrum analyzers and power meters for complete test flexibility |
| Easily controlled from an external computer (via RS-232) or by using the included handheld manual controller |
Vehicle Manufacturing:
| Speeds production by simplifying alignment of the ACC sensor (antenna) when installed on the vehicle |
| Verifies operation under realistic conditions by simulating moving targets (other vehicles or roadside objects) at multiple target distances |
| Characterizes both radar transmitter and receiver performance |
Application: ACC Module Testing
Keycom understands the requirements of ACC
radar module developers and manufacturers.
Test times must be minimized yet
performance must be assured. The ME7220A
can quickly and completely characterize all
three major elements of the ACC system, the
transmitter, receiver and antenna.
Accurate testing of the ACC module requires
accurate alignment of the RTS antenna with
that of the module. The ME7220A RTS
includes a built-in laser to facilitate that
alignment. Quantify module performance at
two ranges with targets that are completely
programmable in size (RCS) and speed. Full
data downloading and archiving is provided
via the RS-232 interface to your external
computer. The built-in RF detector in the
ME7220A delivers pinpoint accuracy when
measuring antenna patterns and radiated
power. The ME7220A also has built in
capability to measure the center frequency of
the modulated radar signal.

Application: On-Vehicle Verification and Alignment
Operating statistics from long-haul truck companies have shown that collision warning and ACC systems can reduce accidents by
as much as 70%. Until now installation and alignment of these systems during vehicle manufacture has been a costly, manual,
time-consuming process even on the lowest-volume vehicle production lines.
When used with your existing vehicle alignment setup, the Keycom ME7220A Radar Test System facilitates alignment of the ACC
module to the vehicle thrust axis, and verifies correct radar operation and antenna alignment. Even within the tight confines of your vehicle production line, simulated targets quickly verify radar operation at both close-in and long ranges.You can adjust the size
and relative speed of either target to accurately verify functionality and alignment without time-consuming drive-by testing.
The instrument-grade quality and calibration of the ME7220A means that your results will be repeatable as well as accurate.
