1 Product Introduction
1.1 Overview
The Radar is developed for the traffic industry by using brand-new software and hardware
technologies. The Radar has 2 models: DHI-ITARD-024MA-T4 (suitable for 4 lanes) and
DHI-ITARD-024MA-T6 (suitable for 6 lanes). With a working frequency that ranges from 24 GHz to
24.25 GHz, the Radar conforms to global frequency standards. You can use the Radar to measure the
information of multiple targets at the same time, including the distance between a target and the
Radar, the angle between a target and the Radar, and target speed. Based on the measuring results,
the Radar provides accurate trigger information.
The Radar adopts the frequency-modulated continuous-wave (FMCW) technology, which allows the
Radar to accurately and quickly distinguish distances and speeds. For angle measurement, the Radar
adopts the multiple-input and multiple-output (MIMO) technology, which allows the Radar to
measure and distinguish angles with higher accuracy. In addition, the Radar is equipped with
advanced tracking algorithm. The algorithm ensures that the Radar can measure the information of
all targets in target-intensive scenarios. With these technologies, the Radar can be used to help
monitor the checkpoints of multiple lanes and collect traffic information, and is particularly suitable
for places with heavy traffic flow.
1.2 Functions
●
You can install the Radar above the lanes or at the side of the lanes.
●
DHI-ITARD-024MA-T4 has a horizontal viewing angle of 60° and can cover 4 lanes.
●
DHI-ITARD-024MA-T6 has a horizontal viewing angle of 120° and can cover 6 lanes.
●
Output trigger information includes lane numbers, vehicle speeds, and vehicle lengths.
●
You can set the trigger distance between 20 m and 55 m. The accuracy is 1 m.
●
You can set the lower limit of the trigger speed.
●
The Radar supports signal processing based on MIMO.
