3.1 Target Simulator Setup

Using a Radar Target Simulator, additional parameters can be tested such as long range SNR. The Target Simulator takes in the TX signal from the DUT sensor and emulates a target at certain distance and velocity and sends the signal back to the DUT sensor. The target simulator can simulate a single object or multiple objects over multiple angles of arrival. The target simulator can also be programmed with various different scenarios that can be used to test target detection and classification algorithms.

Long-range SNR may be an essential production test for certain applications like long range radar. Figure 3-1 shows the hardware test setup using Target Simulator.
