Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-precision satellite navigation, in particular to a control method of anti-jamming weighting induced amplitude and phase distortion for high-precision anti-jamming navigation. BACKGROUND

[0002] The prominent features of high-precision anti-jamming satellite navigation applications such as precision approach and landing of aircraft, carrier-based aircraft landing, formation flight and automatic in-flight refueling of aircraft, rapid direction finding and self-north-seeking of missile launch vehicles / aircraft, etc. are complex interference environment and high requirements for positioning and orientation.

[0003] The complex interference environment mainly manifests in multiple types and changes of interference. From the perspective of interference mechanism, the types of interference include suppression interference, deception interference, and combined suppression and deception interference, among which deception interference is further divided into regenerative and retransmission types. The changes of interference mainly include rapid or slow changes of the number, direction, modulation, frequency, and intensity of interference over time. The requirements for positioning and orientation include real-time or near real-time provision of decimeter / centimeter level positioning services and orientation services better than 1 degree / 0.5 degree, etc.

[0004] High-precision positioning and orientation in a complex interference environment need to solve three strongly coupled problems: complex interference detection and real-time suppression, satellite signal distortion tracing and control, and high-precision positioning and orientation under low distortion.

[0005] Through theoretical derivation, simulation analysis, and experimental verification, the above three problems are decoupled and disassembled into three categories, seven subcategories, and ten sequential topics as shown in the table below.

[0006] Accordingly, ten high-precision anti-jamming navigation invention patents corresponding to the above topics are laid out.

[0007] Table 1 Decoupling and disassembly of high-precision positioning and orientation problems in a complex interference environment

[0008]

[0009] The present application analyzes the second category, the fifth subcategory, and the eighth invention listed in the above table: a control method of anti-jamming weighting induced amplitude and phase distortion.

[0010] High-precision anti-jamming navigation not only needs to exert the beneficial effects of array antenna space-time / frequency domain joint filtering: suppressing strong interference and lifting weak satellite signals in the combined signal composed of satellite signals, noise, and interference; but also needs to control its harmful effects: amplitude distortion and phase distortion (hereinafter referred to as amplitude and phase distortion), which are caused by non-ideal amplitude and phase of the receiving channel and amplitude and phase weighting of anti-jamming processing, etc.

[0011] The distortion introduced by the amplitude and phase non-ideality of the receiving channel can be measured offline and controlled online, as described in detail in the second type, fourth sub-type, and sixth invention of the control method of the amplitude and phase distortion introduced by the receiving channel. The distortion introduced by the amplitude and phase weighting of the anti-jamming processing needs to be calculated and controlled online, as described in detail in the invention.

[0012] The amplitude and phase weighting of the anti-jamming processing can be divided into the amplitude and phase weighting of the adaptive nulling anti-jamming processing and the multi-beam anti-jamming processing. The combined signal formed by the navigation signals broadcast by all visible satellites, the interference emitted by the interference source, and the noise is formed into a combined signal vector after passing through the receiving channel composed of each array element and each radio frequency channel. The adaptive nulling anti-jamming processing uses an optimal anti-jamming weight vector to perform amplitude and phase weighting on the combined signal vector and sum it up to obtain a combined satellite signal in which the interference is effectively suppressed. Because the anti-jamming weight vector used for amplitude and phase weighting is the same vector, the same amplitude and phase distortion is introduced to each satellite signal. The multi-beam anti-jamming processing uses L optimal anti-jamming weight vectors (facing a certain visible satellite) to perform amplitude and phase weighting on the combined signal vector and sum it up to obtain a certain visible satellite signal that is highly purified (high signal-to-noise ratio reception and effective interference suppression). Because the anti-jamming weight vectors used for amplitude and phase weighting are not the same, the amplitude and phase distortion introduced to each satellite signal is not the same.

[0013] The existing control method of the amplitude and phase distortion introduced by the anti-jamming weighting mainly includes two types. One type is the anti-jamming weight vector optimization method, which selects an appropriate optimal criterion to reduce the amplitude and phase distortion introduced by the anti-jamming processing, but cannot completely eliminate the amplitude and phase distortion. The other type is the anti-jamming weight vector real number method, which avoids the phase weighting of the anti-jamming processing by constraining the elements of the anti-jamming weight vector to be real numbers, thereby cutting off the phase distortion approach, at the cost of sacrificing half of the anti-jamming (spatial) degrees of freedom. That is, The array antenna originally can resist interference from different directions, and after the additional constraint, can only resist interference from different directions.

[0014] The existing two types of control methods of the amplitude and phase distortion introduced by the anti-jamming weighting cannot meet the requirements of the satellite signal amplitude and phase distortion control of high-precision anti-jamming navigation.

[0015] Based on this technical background, the invention studies the control method of the amplitude and phase distortion introduced by the anti-jamming weighting for high-precision anti-jamming navigation. SUMMARY
