E8708A Radar Target Simulator

E8708A Radar Target Simulator

76 GHz to 81 GHz

Introduction

Radar, lidar, and cameras, these are some of the sensing technologies that is driving today’s market for Advance Driver Assistance Systems (ADAS), as we move into the future of autonomous vehicles. The demand keeps growing, with more investments into development and manufacture of the latest sensing technologies to fit all transport methods. For radar, the technology has narrowed down to the use of 77 GHz for the far range radar, and 79 GHz for the short to medium range radar, replacing the 24 GHz radar. May it be in emergency braking systems, adaptive cruise control or forward/rear collision warning, without a doubt, the radar sensor serves to ensure a safer drive for passengers and road users alike. The safety nature of automotive radars translates to a fast, accurate and reliable test solution for product test teams, regardless if they are in manufacturing or design verification. A purpose-built tool that will accurately and repeatedly simulate targets to test radar units, and to take it further, with features that will help to provide further measured insight while simulating the targets. This is what the Keysight E8708A offers, simple and straightforward target simulation, with a robust design that covers both 77 GHz and 79 GHz radar units.

Product Description

Enhanced to cover from 76 GHz to 81 GH, the latest generation E8708A Radar Target Simulator (RTS) is separately optimized from 76 GHz to 77 GHz and 77 GHz to 81 GHz, with newly added features to enhance usability. The E8708A is offered with full simulation range from 4m to 300m; or in fixed ranges defined by customers, helping to scale the price vs usage model for customers. A newly added in-built signal analyzer option, enhances the usability for customers, allowing average power and occupied bandwidth measurements to be done within the same box. Configurations requiring Doppler no longer requires an external signal generator, instead, it is now an in-built option within the RTS. The E8708A is available in either dual-horn - Tx and Rx, or a single horn configuration with built-in circulator.

The base E8708A system will provide simulation of both range and radar cross section. Signal analyzer and Doppler simulation features are optional. Figure 1 (above) described the solution in more detail together with the connection method. A minimum physical distance of 1m between the E8708A RTS and the device-under-test (DUT), helps to reduce valuable manufacturing floor space, Figure 2 (below).
