Like the noise signal, the chaotic signal exhibits continuous power spectrum, initial-value sensitivity, ergodicity, and aperiodicity, and therefore chaotic signal possesses good range and velocity resolutions, thumbtack ambiguity function, excellent antijamming
ability, and electromagnetic compatibility.
"These satellites will provide greater accuracy and improved antijamming
capabilities, making them more resilient."
In this study, we investigated the problem of shift-frequency interference with radar, where the Doppler shift value estimation is the key for antijamming
techniques, and a method for specific Doppler confirmation processing is provided from the perspective of the waveform.
The flight control of the eight-rotor UAV studied in this paper adopts the method of backstepping control and PID control and through the hybrid control method attempts to control the eight-rotor UAV in different environments and improve the flight stability and antijamming
capability of the UAV.
Because of the wider bandwidth, the BOC signal has a greater antijamming
capability than the DSSS signal.
Although chaotic systems in general and noncoherent chaotic systems in particular are partly designed for the antijamming
(AJ) purpose, the AJ performance of a noncoherent chaotic system is only carried out in .
He has published more than 20 articles in the area of wireless communications, holds two patents, and has taught courses on wideband wireless communication and antijamming
The proven resiliency, reliability and antijamming
capabilities of the Link 16 terminal (first developed in the 1970's and operationally deployed with the US military since the mid-1980's) plus its ability to be used on aircraft, ships, ground platforms and by dismounted war fighters to exchange data is certainly useful to help disperse the "fog of war."
As part of its offset strategy, the Australian Defence Force should pursue a robust and cost-effective solution to protect military capabilities from GPS interference: high-performance GPS antijamming
devices that allow GPS receivers to acquire and track satellite signals so the Australian Defence Force can retain the ability to determine accurate battlefields positions.
Civilian RF signals rarely use antijamming
or antispoofing techniques.
It is obvious that this architecture is a comprehensive use case of three technologies, combining their advantages in capacity, flexibility, and antijamming
From Figure 3, it is seen that the convergence performance of the PSO algorithm is good, and its antijamming
capability is realised.
