The microwave radar module has RF signal emitting and receiving part to emit microwave signal to the surface of the object via the antenna emitting vibrator and to receive the physical signal of the object via the receiving vibrator, and microwave circuit to shape the received electromagnetic wave, filter and filter the non-reflected signal. The signal processing sub-board performs primary signal processing on the output and received microwave radar signals and transmits the physical signals of the processed object to the signal processing part. The video control main board is respectively combined and distributed on the plurality of sub-boards and is connected with the camera through a connecting line to process a target shot by the camera. The video camera shoots a target to carry out algorithm identification, and the type of the object (such as a truck, a car, a motorcycle and the like) is measured and calculated. The signal processing board analyzes and processes physical data (including movement direction, distance, speed, direction and the like of a detection target) transmitted by the microwave radar and information of primary signal processing such as object properties and types and the like transmitted by the video control board, judges by combining received external signal information, and outputs instruction signals such as alarm images, sounds, light and the like to the outside after fusion.
The signal processing board 33 outputs high and low level signals to drive the warning light to be on or flash in a long time by combining the received information of the target speed, the moving direction, the distance, the angle and the like and sending instructions such as a steering light signal by the vehicle; and driving the buzzer to alarm or not. When a moving object such as a vehicle or a pedestrian, an electric vehicle, a motorcycle and the like enters a detection range, the LED warning lamp is on for reminding; if the driver dials the turn signal lamp to change the lane, the warning lamp flickers, and the buzzer sends out continuous alarm sound to warn and remind the driver. In addition, the embodiment also has the following beneficial effects: (1) the radio frequency board 31 exclusively performs transmission and reception of radio frequency signals. The gain (signal strength) of the microwave radar antenna is mainly determined by the area size of the transmitting element and the receiving element of the microwave radar antenna.

The conventional microwave radar plate cannot be reduced in size, so that the cost is high. Only the radio frequency part of the micro microwave radar module needs to adopt expensive high-frequency plates, the adapter plate 32 and the signal processing plate 33, and only the common FR4 plate is adopted. The cost can be greatly reduced.
Through installing two miniature millimeter wave radar probes below the 2 shells of fender about the vehicle, can accurate detection from vehicle left and right sides rear vehicle and pedestrian that are close to etc.. When moving vehicles (including automobiles, motorcycles, bicycles and the like) or pedestrians enter the detection range of the microwave radar on the left side or the right side, the LED lamps on the fender 2 of the vehicle on the same side (the LED lamps can also be arranged on the shells of the fender 2, the triangular positions of the tweeters on the inner sides of the doors of the vehicle, the A columns of the vehicle and the like) can be lightened for a long time, and early warning prompt is carried out on a driver; if a driver dials a steering lamp to prepare for lane changing, the LED light is changed from long-time lighting to flashing, and the buzzer sends out continuous alarm sound to give an early warning prompt to the driver, so that lane changing accidents are prevented.
The process for additionally installing the microwave radar video fusion detector 3 on the fender of the automobile comprises the following steps:
firstly, only a proper position is selected on the outer surface of the automobile fender 3 (fender), and a radar video fusion probe (radar antenna) and a high-definition camera which are simply installed are pasted on the automobile fender (completely adhered and fixed after a power-on test is completed).
And secondly, adjusting the radar irradiation angle by combining the edge line of the vehicle body as a reference object.
And thirdly, detaching the lens of the rearview mirror 2, and connecting the steering lamp triggering wire harness of the radar system to the anode of the steering triggering wire of the rearview mirror 2. LED warning lamp bead is pasted on the inner side of 2 pieces of glass of the rearview mirror (or the upper position of the shell of the rearview mirror 2)
Fourthly, a radar power line and a signal line penetrate into the vehicle body 1 through a hose at the front door side. Place buzzer under the direction platform, hidden installation to it is fixed.
Inserting the system safety piece into the original vehicle safety reserved position, and connecting the negative pole of the radar system with the vehicle body 1 to be grounded.
And sixthly, electrifying and testing the detection range of the radar. After the radar angle is adjusted, the mounting and fixing base is fully and completely bonded with the fender to be fixed.
