Embodiment approach

[0101] For the first implementation, see figure 2 The "conical 3D three-transmitter four-receiver single millimeter-wave radar sensor" is the same as the above-mentioned figure 1 The only difference in the "rectangular three-transmission and four-receiver single millimeter-wave radar sensor" is that each series-fed microstrip antenna Tx1, Tx2, Tx3; the width of the rectangular microstrip unit antenna in Rx1, Rx2, Rx3, Rx4 is Taylor ( Taylor) algorithm is modified, so that the side lobe of the transmitted signal on the E plane has a larger attenuation than the main lobe, thereby improving the signal-to-noise ratio of the millimeter-wave radar sensor system and improving the technical effect of the millimeter-wave radar sensor system performance. For the second implementation, see image 3 The "rectangular impedance matching three-dimensional three-transmitter four-receiver single millimeter-wave radar sensor" and figure 1 The only difference in the "rectangular three-transmi...

Abstract

The invention discloses a device applied to a rectangular micro-strip millimeter-wave radar sensor, and belongs to the technical field of millimeter-wave radar sensors. The device comprises that Xn first series feed micro-strip antennae are correspondingly arranged in M lines of millimeter-wave series feed transmitting antenna arrays, and each first series feed micro-strip antenna is connected with the transmitting end of a millimeter-wave radar chip; Yn second series feed micro-strip antennae are correspondingly arranged in W lines of millimeter-wave receiving series feed antenna arrays; andeach second series feed micro-strip antenna is connected with the receiving end of the millimeter-wave radar chip. The W lines of millimeter-wave receiving series feed antenna arrays and the M lines of millimeter-wave series feed transmitting antenna arrays are arranged on the same layer of a printed circuit board, are cooperated or are independently taken as the transmitting antenna arrays and also as the receiving antenna arrays. By use of the device, the technical effects that the transmission of disturbed millimeter-wave signals is avoided and the millimeter-wave radar sensor can be manufactured on the same layer of printed circuit board can be achieved.

Description

technical field [0001] The invention belongs to the technical field of millimeter-wave radar sensors, in particular to a device applied to rectangular microstrip millimeter-wave radar sensors. Background technique [0002] Millimeter wave is a radar electromagnetic wave with a working frequency between 30GHz and 300GHz. When the electromagnetic wave encounters an object, it will generate a reflected wave. By capturing the reflected signal, the radar system can determine the range, speed and angle of the object. Since the transmission wavelength of millimeter-wave radar is in the millimeter range, it not only has submillimeter-level detection accuracy, but also can penetrate certain materials, and is widely used in automotive, drone and medical fields. [0003] For existing technologies applied to millimeter-wave radar sensors, millimeter-wave radar transceiver modules are usually packaged in one or several unit chips. In addition to the technical characteristics unique to or...
