Embodiment Construction

[0026] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0028] This design can be applied to devices with strict restrictions and requirements on time precision and devices with modular systems. The signal processing module dynamically measures the delay of the test signal, and calculates the sum of each possible time delay mentioned above, that is, T (delay time). When formally measuring the distance, subtract the measured delay time T (delay time) from the total time T (total), and then multiply...

Abstract

The invention discloses a closed-loop adaptive ranging working method. A signal processing module simulates the closed-loop transceiving process to form a closed-loop test. During startup each time, the delay of test signals is automatically measured dynamically and corrected, so that a corrected value is more accurate, and the ranging accuracy is improved. In the design, a transmitting end and areceiving end simulate the closed-loop transceiving process, the test signals are transmitted to an antenna port through a transmission channel, and control signals are fed back to a receiving channel to form the closed-loop test. The algorithm is solidified in the signal processing module and is completely carried out automatically, so the test time is saved, the test method is simplified, and the efficiency and system reliability are greatly improved.

Description

technical field [0001] The invention relates to a closed-loop self-adaptive ranging working method. Background technique [0002] The traditional test method is to use special test instruments to measure each module inside the device (including signal processing module, frequency synthesis module, transceiver module, connecting cable, etc.), and then accumulate to obtain the internal delay and correct it. [0003] This method is cumbersome to test and can only be used for individual measurements. When modules are interchanged, re-measurement is required. The test efficiency is extremely low, and it is greatly affected by the external environment (such as temperature, climate), and the distance measurement accuracy is difficult to meet the target. Require. Contents of the invention [0004] However, the algorithm in this design will automatically send data for multiple tests and automatically configure the correction value every time the algorithm is turned on. The signal ...
