Problems solved by technology
Based on this distance requirement, it is necessary to increase the number of array elements of the antenna to increase the gain, thereby increasing the radar detection range, but this will increase the size of the antenna and reduce the beam width of the antenna elevation plane; moreover, the radar is installed on the corner of the vehicle, The requirement for the detection distance in the normal direction is not high, and the traditional design will cause a waste of gain in the normal radiation direction of the antenna

Embodiment Construction
[0034] In order to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in contemplation, and It is an embodiment of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.
[0035] This patent proposes a method of implementing a millimeter wavelength radar power coverage, including the following steps:
[0036] S1: Defines the power of millimeter wave angle radar power coverage, design the initial shape of the radar antenna direction map and the beam modification requirements of the antenna;
[0037] S2: The transmitted (GTX) and reception (GRX) gain requirements required to be calculated according to the radar system link formula (eg figure 2 Indicated by it);
[0038] S3: The three transmit channels simultaneously transm...

The invention provides a millimeter wave angle radar power coverage range implementation method, which realizes the power coverage range requirement of angle radar on target detection right behind and on the side of a vehicle by shaping a radar antenna beam, and adopts a simultaneous MIMO (Multiple Input Multiple Output) transmission mode to modulate the phase of a transmitted waveform. The transmitting power of the radar is further improved, and the signal-to-noise ratio is further improved, so that accurate detection of the angle radar on targets in the whole FOV (field of view) range at different mounting angles is met.
Description
Technical field [0001] The present invention relates to the field of millimeter wave angle radar technology, in particular, to a mm wave angle radar power coverage implementation method. Background technique [0002] The millimeter wave radar is an indispensable part of the smart driving assistance system (ADAS), which makes the automotive active safety warning system have been upgraded, providing safety security to car driving, to a certain extent, to a certain extent, the driver's life and property Not infringed. Apply millimeter wave anti-collision radar to the car, which can be convenient to detect information such as the distance, speed and angle of the target. Once a risk can promptly propose a warning in a timely manner. [0003] Due to the maintenance of the power coverage of the angle radar mainly in the front and side of the vehicle, the detection distance target of the front rearward needs to reach 90 ~ 100m, and the side detection distance target needs to reach 50 to ...
