Front radar sensor (2024)

The new front radar sensor detects objects and people quickly, precisely, and reliably thanks to its long detection range and outstanding angle separability, not to mention its wide field of view. The own chirp sequence modulation improves the sensor perception by robust reflections. This enables the sensor to detect objects’ positions, relative speeds, and directions of motion with extremely high precision. These properties make the radar sensor ideal for chaotic urban traffic, where multiple objects and people can be simultaneously detected, differentiated, and for example, tracked before emergency braking is initiated as needed. Thanks to radar sensor technology, this also works in poor visibility.

The front radar plus is also beneficial for driver assistance functions, and partially automated functions. Due to the sensor’s long detection range, these functions can be realized at speeds of up to 210 km/h. The sensor’s properties ensure greater safety, comfort and convenience when driving.

With the front radar sensors, it is possible to detect the position, relative speed, and direction of movement of other traffic participants and objects from a distance very reliably and even at higher speeds with just one radar measurement. The front radar sensor premium impresses in particular with its improved vertical and horizontally separability. This makes it possible to unambiguously classify even small objects and vulnerable road users. The sensor detects, for example, that a motorcycle rider is overtaking a truck and reliably identifies both objects despite the small distance between them. When the vehicle approaches a tunnel, the radar can clearly identify a motorcycle rider traveling in front since it is able, thanks to its outstanding horizontal separability, to detect the space between the motorcycle and the ceiling of the tunnel. These properties allow for a direct height measurement and better classification of traffic participants (vehicles, pedestrians, cyclists) and potential obstacles such as tires or pallets in the lane.

What does front radar sensor blocked mean? ›

If this symbol and the message Radar sensor front Sensor blocked See Manual are displayed in the instrument panel, it means that the radar sensor is unable to detect other vehicles, cyclists, pedestrians and large animals in front of the vehicle and that the vehicle's radar-based functions may be obstructed.

How to fix front radar obstruction? ›

Remove any objects that may be obstructing the radar sensor. If there is snow, ice, mud, or debris on the front bumper, remove it. If there is a license plate bracket or other object mounted on the front bumper that is blocking the radar sensor, try to reposition it or remove it altogether.

Where is the front radar sensor on a Mazda CX-9? ›

The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead sent from the radar sensor. The following systems also use the radar sensor (front). The radar sensor (front) is mounted behind the radiator grille.

How to clean front radar sensors? ›

In order for the radar units and sensors to function properly, they must be kept free of dirt, ice, snow, etc. and washed regularly with water and car washing detergent. It is important that the surfaces in front of radar units and sensors are kept clean.

What does it mean when the front radar is obscured? ›

A: Forward safety system disabled. Camera obscured. When the front windshield where the front view camera is located, front radar cover, bumper or sensor is covered with foreign material, such as snow or rain, it can reduce the detecting performance and temporarily limit or disable Forward Collision-Avoidance Assist.

What is the function of the front radar sensor? ›

The front radar sensor facilitates fast, precise, and resilient object detection and tracking thanks to its long detection range, wide field of view, outstanding angle separability, and own chirp-sequence modulation feature. This makes it ideally suited to complex traffic scenarios.

Where is a front sensor on a car? ›

A car sensor is an electronic device mounted on a car's front bumper. It uses advanced technology to detect obstacles ahead and alert the driver. The sensor can detect objects such as other cars, pedestrians, or even animals.

What is a radar sensor in a car? ›

An automotive radar is a radio detection and ranging (radar) vehicle sensor that uses radio waves to measure the positions and trajectories of vehicles, people, animals, and other objects around it. It works by transmitting radio waves in the direction of interest.

Where is Mazda radar sensor located? ›

The radar sensor (front) is mounted behind the front emblem. If “SBS, MRCC, DRSS Radar blocked” is displayed in the multi-information display of the instrument cluster, clean the area around the radar sensor (front).

Where are the sensors on a Mazda? ›

The radar sensors (rear) are installed inside the rear bumper, one each on the left and right sides. Refer to Radar Sensors (Rear) (Search). The ultrasonic sensors (rear) function by detecting the ultrasonic waves reflected off obstructions at the rear sent from the ultrasonic sensors.

Does Mazda have front sensors? ›

Traffic Jam Assist, front and rear parking sensors and 360° View Monitor are all included within Mazda CX-50 2.5 Turbo Premium Plus models.

What is radar blockage? ›

The automotive radar may sometimes be covered with snow, dirt, or other obscurants, a state which we refer to as radar blockage. The radar must be able to detect blockage as a fault state.

What blocks radar signals? ›

Mechanical jamming devices include chaff, corner reflectors, and decoys. Chaff is made of different length metallic strips, which reflect different frequencies, to create a large area of false returns in which a real contact would be difficult to detect.

What is the function of the front radar? ›

Front radar sensors also play a part in active ADAS systems. These advanced driver assistance systems rely heavily on sensor data to make decisions and control the vehicle's movements. For example, in automatic emergency braking (AEB) systems, front radar sensors scan the road ahead and detect potential collisions.
