Embodiment Construction

[0028] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0029] In radar detection technology, the dimension corresponding to each pulse in the radar signal is usually called the fast time dimension, and the dimension corresponding to each pulse sequence in the radar signal is called the slow time dimension. The pulse system radar does not only transmit one pulse, but usually transmits a continuous pulse sequence, for example, M pulses are...

Abstract

The present application is applicable to the technical field of radar detection, and provides a radar anti-jamming method, a terminal device and a storage medium, wherein the above method includes: when switching the transmitting antenna of the radar, performing a radar signal on the radar signal transmitted by the switched transmitting antenna. first initial phase encoding; transmitting the radar signal encoded by the first initial phase through the switched transmit antenna; receiving echo signals; performing corresponding initial phase compensation on each data frame in the echo signals. The radar anti-jamming method, the terminal device, and the storage medium provided by the embodiments of the present application take the transmitting antenna of the radar as the spatial dimension, and implement the corresponding phase encoding of the radar signal transmitted by the transmitting antenna, thereby realizing the radar signal in the spatial dimension. Anti-jamming coding.

Description

technical field [0001] The application belongs to the technical field of radar detection, and in particular relates to a radar anti-jamming method, terminal equipment and a storage medium. Background technique [0002] Various electronic devices that use electromagnetic waves for communication or obstacle detection, such as radar devices, especially vehicle-mounted radar devices, are increasingly used in people's daily lives. This makes people's living space, such as the sky above urban roads, full of various electromagnetic radio frequency signals. In the space where many electromagnetic radio frequency signals coexist, the communication process of different electronic devices will inevitably interfere with each other. This requires radar equipment, especially vehicle-mounted radar equipment, to have corresponding anti-interference capabilities to avoid or alleviate electromagnetic interference. coming impact. [0003] The existing automotive anti-collision radar has two ...
