10 June 2021 Report Issue Topic CR5CBCC User Manual Explanation of CW Radar function Continuous-wave radar is a type of radar system where a known stable frequency continuous- wave radio energy is transmitted and then received from any reflecting objects. Continuous- wave (CW) radar uses Doppler, which renders the radar immune to interference from large stationary objects and slow moving clutter. - Page 4 Report Issue Topic CR5CBCC User Manual frequency shift. This allows range and velocity to be found with one radar set. Triangle wave modulation can be used to achieve the same goal. As shown in the figure the received waveform (green) is simply a delayed replica of the transmitted waveform (red).

Page 5: Operation Principle Of The Cr5Cbcc
The radar sensor‘s main task is to detect objects and measure their speed and position relative to the movement of the vehicle in which it is mounted. To do this, the CR5CBCC senses targets by emitting many short frequency modulated waves using the transmit antennas while receiving waves reflected by targets using the receive antennas. -
Page 6: Areas Of Application
CR5CBCC operates in long-range mode, monitoring area behind vehicle for small, fast approaching targets (like motorbikes). Areas of application The CR5CBCC is the base for range of safety and driver assistance functions. In particular, the CR5CBCC can be used for the following functions: 4.2.1... -

Page 9: Radar Cone
Report Issue Topic CR5CBCC User Manual The radar sensor performance should be influenced as low as possible by the installation behind a fascia. Therefore the two-way radar loss by the fascia should be as low as possible and the reflection attenuation must fulfill the requirements listed below. - Page 10 10 June 2021 Report Issue Topic CR5CBCC User Manual Figure 3: Footprint of the radar cone. For better visibility, the footprint is shown on top of the sensor housing. Radar cone definition for covered installation (CR5CB): The horizontal opening angle depends on the angle range that is evaluated by the sensor in azimuth and elevation, whereby the opening angle of the radar cone has to be larger than the angle range that is evaluated.
