Embodiment Construction

[0031] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a detecting device based on combined barker code burst pulses. The device comprises a sub-pulse generation unit, a pulse combination unit, a pulse compression unit, a transmission unit, a receiving unit and a processing unit, wherein the sub-pulse generation unit is coupled with the pulse combination unit; the pulse combination unit is coupled with the sub-pulse generation unit and the pulse compression unit; the pulse compression unit is coupled with the pulse combination unit, the transmission unit and the processing unit; the transmission unit is coupled with the pulse compression unit; the receiving unit is coupled with the processing unit; and the processing unit is coupled with the receiving unit and the pulse compression unit. The device provided by the invention solves the problem that the conventional detecting device cannot eliminate fuzzy distance and fuzzy speed at the same time.

Description

technical field [0001] The invention relates to the field of electromagnetic wave detection, in particular to a detection device based on combined Barker code burst pulses. Background technique [0002] At present, electromagnetic wave detection devices mostly use the Doppler effect for positioning, speed measurement, and distance measurement. Specifically, the PRF (pulse repetition frequency) used by conventional detection devices ranges from several hundred Hz to hundreds of thousands of Hz. , and the choice of PRF has a great impact on the performance of the detection device. According to whether the PRF makes the observation distance and Doppler frequency ambiguous, it can be divided into three basic types: low PRF, medium PRF, and high PRF; among them, [0003] The advantage of low PRF is that the target with high Doppler frequency appears in the clutter-free spectrum area, and high average power can be obtained. When the main lobe clutter is suppressed, the target echo...
