低頻雷達可以在極端天氣條件下可靠地偵測電介質目標物，包括汽車、火車、卡車和貨物。高頻雷達可以偵測的目標物更加廣范，在大多數應用中（包括室外）比超聲波感測器更堅固耐用。此外，基於雷達的感測器非常適用於移動設備上避免碰撞，例如堆高機、叉車和採礦車輛或港口機械，如運送裝置、搬運裝置和發運裝置。

Radar Sensors Improve Reliability and Operational Efficiency

On their own, radar sensors are a durable and reliable method for object and vehicle detection, collision avoidance, positioning feedback, tank level measurement, and more. They can do all of this either indoors or out, at short ranges or long distances, even when the environment presents unusual challenges that might trip up other sensor technology. But when incorporated as part of an automated system comprising sensing, real-time indication, and instant feedback, radar becomes an incredibly powerful—and necessary—component of a reliable and efficient operation.

Variations in radar technology offer distinct advantages depending on their frequency. Certain radar frequencies excel at detecting high dielectric objects such as cars, trains, trucks, and cargo, even under extreme weather conditions. Other radar frequencies can detect a broader array of objects and generally outperform ultrasonic sensors in most applications, including outdoor environments. Radar-based sensors are particularly well-suited for collision avoidance in mobile equipment like reach stackers, forklifts, and mining vehicles, as well as port machinery such as carriers, handlers, and shippers. Banner offers a variety of products across different frequencies, ensuring the right sensor for each specific application.

Radar Technology

Sensing in particular environments can present a number of challenges that don’t exist in close-quarter, climate-controlled settings. Temperature extremes, precipitation, swirling dust and dirt, objects in motion both near and far, and a variety of surfaces and materials require a device able to sort through it all. There’s one type of device that can resist all these problems and detect only what’s necessary whether indoors or outside—the radar sensor.

Radar stands for Radio Detection And Ranging. It’s an object detection system in which electromagnetic radio waves are sent out by an emitter and used to determine the distance, position, and presence of an object. Banner uses two types of radar sensor technologies: FMCW and pulsed.

Frequency Modulated Continuous Wave

Frequency Modulated Continuous Wave (FMCW) radar sends out a continuous stream of radio waves while constantly listening for any reflected waves. The difference between the frequencies of the emitted and reflected signals can be used to calculate a distance. FMCW is considered to be more accurate than pulsed radar.

Pulsed Radar

Pulsed radar emits radio waves in short bursts, then listens for a reflected signal to return to the receiver before sending out another pulse. A target’s distance can be calculated using the time it takes for a pulse to be emitted, reflected, and returned to the receiver. Pulsed signals use less energy than a continuous one, so the sensor will consume less power.

Detection Abilities

An object’s shape, size, material, and angle of incidence influence its ability to be seen by radar. These factors determine an object’s radar cross section, which is how detectable an object is by radar. Large targets presented perpendicularly will be easier to detect than smaller targets or those presented at an angle. Materials that have a high dielectric constant, like metal or water, have a dense electric field and can more easily reflect electromagnetic waves. They will return a stronger radar signal than materials with a lower dielectric constant, such as organic material or plastic, whose lower-density electric fields permit more electromagnetic waves to pass through without reflection.

Operating Frequency

Another crucial part of radar is the operating frequency. Different frequencies are able to detect different types of materials. Sensors with 24 GHz radar can perform long-range sensing with high immunity to ambient environmental conditions, but have a coarse resolution and are limited to detecting targets with a large radar cross section. Sensors that use 60 GHz or 122 GHz radar have shorter ranges, but are more accurate and can detect both high and low dielectric materials.

Uses of Radar

While familiar uses of radar include tracking aircraft and checking driving speeds, radar sensors are valuable in many industries. They can be used on vehicles for collision avoidance on cranes to maintain safe distances between them and their cargo, and detect the presence of vehicles in a parking garage or drive thru.

Radar sensors are also a key component of industrial automation. For example, radar sensors can measure solid or liquid volumes in containers, then communicate those fill levels to nearby workers via illuminated indicators, or through a cloud service (such as Banner CDS) to employees monitoring remotely. They can let warehouse workers know when trucks have arrived, or tell robotic picking arms if items are on a conveyor belt.
