[0118] Furthermore, the re-optimization of the corresponding transmission code is triggered based on the comparison between the code similarity and the preset code similarity threshold; the re-optimization of the corresponding transmission code is monitored in real time until the code similarity of each transmission code is lower than the preset code similarity threshold; when the code similarity of each transmission code is lower than the preset code similarity threshold, the corresponding transmission channel is matched according to each transmission code to ensure the accuracy of the transmission channel. At the same time, each transmission code is introduced, and each transmission code is separated and controlled, and the transmission channel is initially separated.

[0119] refer to Figure 6 , S15: separate and arrange each transmission channel, match the corresponding channel optimization logic based on the separation coefficient between two adjacent transmission channels and the load of the transmission channel, and dynamically adjust the interference coefficient of the two adjacent transmission channels according to the channel optimization logic;

[0120] In the specific implementation process of the present invention, the specific steps may be:

[0127] In the embodiments of the present application, each transmission channel is frozen; each transmission channel is monitored in real time, and two adjacent transmission channels are located, the two adjacent transmission channels are introduced, and further processing of the two adjacent transmission channels is achieved.

[0128] At this time, the separation coefficient between two adjacent transmission channels is collected; the separation coefficient between two adjacent transmission channels and the load of the transmission channels are associated; the corresponding channel optimization logic is matched according to the separation coefficient between two adjacent transmission channels and the load of the transmission channels, and the separation coefficient between two adjacent transmission channels and the load of the transmission channels are introduced. Multiple interactions are performed on the separation coefficient between two adjacent transmission channels and the load of the transmission channels to ensure the accuracy of the channel optimization logic.

[0129] At this time, the interference coefficient of the two adjacent transmission channels is dynamically adjusted according to the channel optimization logic, thereby realizing dynamic adjustment of the interference coefficient of the two adjacent transmission channels, so as to facilitate the management and control of the two adjacent transmission channels and ensure the interval and anti-interference of the two adjacent transmission channels.

[0130] refer to Figure 7 , S16: If the interference coefficient is within the interference warning range, triggering a multi-layer pseudo-random code according to the interference coefficient and the corresponding transmission channel, and dynamically adjusting the interference coefficients of two adjacent transmission channels based on the multi-layer pseudo-random code and the corresponding multiple transmission signal phases;

[0137] S166: Dynamically adjust the interference coefficients of two adjacent transmission channels based on the multi-layer pseudo-random codes and the corresponding phases of multiple transmission signals.

[0138] During the specific implementation of the present invention, each transmission channel is separated and arranged, and the corresponding channel optimization logic is matched based on the separation coefficient between two adjacent transmission channels and the load of the transmission channel, and the interference coefficient of the two adjacent transmission channels is dynamically adjusted according to the channel optimization logic; if the interference coefficient is in the interference warning range, the multi-layer pseudo-random code is triggered according to the interference coefficient and the corresponding transmission channel, and the interference coefficient of the two adjacent transmission channels is dynamically adjusted based on the multi-layer pseudo-random code and the corresponding multiple transmission signal phases, which is compatible with the overall consideration of the separation coefficient between two adjacent transmission channels and the load of the transmission channel, ensuring the accuracy of the channel optimization logic, and dynamically adjusting based on the channel optimization logic and the interference coefficient of the transmission channel, realizing further control of the interference coefficient of the transmission channel, so as to ensure the non-interference effect of each transmission channel, improve the control effect of interference control of multiple millimeter-wave radars, and further realize the stable use of multiple millimeter-wave radars in the same space.

[0139] At this time, the interference coefficient is frozen; the interference coefficient is monitored in real time; the interference coefficient is dynamically compared with the interference warning range, thereby achieving real-time comparison between the interference coefficient and the interference warning range.

[0140] Furthermore, if the interference coefficient is within the interference warning range, multiple interactions are performed on the interference coefficient and the corresponding transmission channel; multiple layers of pseudo-random codes are triggered based on the multiple interactions of the interference coefficient and the corresponding transmission channel, and multiple interactions of the interference coefficient and the corresponding transmission channel are introduced to achieve multiple interactions of the interference coefficient and the corresponding transmission channel, thereby ensuring the accuracy of the multiple layers of pseudo-random codes.

Based on the channel optimization logic and the interference coefficient of the transmission channel, dynamic control is performed to achieve further control of the interference coefficient of the transmission channel to ensure the non-interference effect of each transmission channel, improve the control effect of interference control of multiple millimeter-wave radars, and further realize the stable use of multiple millimeter-wave radars in the same space.

[0142] In another embodiment of the present invention, the phases of the transmission signals of multiple transmitters of the millimeter wave radar are phase modulated by multiple sets of pseudo-random codes, that is, a pseudo-random code generator is used to generate N sets of mutually orthogonal pseudo-random codes, and each set of pseudo-random codes controls a phase modulator in a transmitter according to a fixed timing. N transmitters can transmit radar signals at the same time, and each set of radar signals is phase modulated by a different pseudo-random code controlling the phase modulator.

[0143] The millimeter wave radar has M receivers, each receiver receives radar signals from N transmitters at the same time, and N phase modulators are placed in parallel in each receiver. The phase of each phase modulator is controlled by the aforementioned N groups of pseudo-random codes according to the aforementioned fixed timing. The output ends of the N phase modulators can output radar intermediate frequency signals transmitted by the N transmitters and received by the receiver. In this way, it is possible to recover N*M intermediate frequency signals transmitted by N transmitters at the same time and received by M receivers at the same time.

[0144] The signals are detailed below:

[0145] The signal generated by the voltage-controlled oscillator is LO. The transmitted signal after the LO signal is phase modulated according to pseudo-random code 1 in transmitter 1 is TX1. The transmitted signal after the LO signal is phase modulated according to pseudo-random code 2 in transmitter 2 is TX2. The transmitted signal after the LO signal is phase modulated according to pseudo-random code N in transmitter N is TXN. These transmission signals TX1, TX2, ..., TXN are reflected back after hitting obstacles. Each receiver (receiver 1, receiver 2, ..., receiver M) receives N transmission signals at the same time. Without loss of generality, receiver 1 is taken as an example. Receiver 1 receives the transmission signals RX1 (TX1, TX2, ..., TXN) from N transmitters. The signals are mixed and filtered and then input into the parallel phase modulator. The output signal of the phase modulator that modulates the phase according to pseudo-random code 1 is the transmission signal of transmitter 1 received by receiver 1, the output signal of the phase modulator that modulates the phase according to pseudo-random code 2 is the transmission signal of transmitter 2 received by receiver 1, and the output signal of the phase modulator that modulates the phase according to pseudo-random code N is the transmission signal of transmitter N received by receiver 1. Thus, the transmission signals of N transmitters received by all M receivers can be obtained, which is a total of N*M intermediate frequency signals.

[0146] Advantages of the invention:

[0147] Through the pseudo-random code modulation of the transmitter phase, multiple transmission channels can be separated. As long as the pseudo-random code is long enough, any number of transmission channels can be separated.

[0148] All transmitters transmitting simultaneously can greatly improve the signal-to-noise ratio, shorten radar transmission time, and reduce mutual interference between multiple radars;
