While it may not be possible to eliminate entirely the effects of CMs, their impact. The CM designer attempts to exploit weaknesses in the radar design, while the radar designer attempts to anticipate potential CMs and provide CCMs that reduce their effectiveness. Book Description This is the very first book to present the network radar countermeasure system. Special CM circuits, techniques, and actions, such as sidelobe blankers, sidelobe cancellers, added transmitter power for burnthrough, and passive tracking.

Examples are use of high-energy waveforms and pulse integration, and precise tracking and radar signature measurements. Radar operating modes and procedures that respond to the countermeasures employed. Examples are low antenna sidelobes and high-resolution waveforms. Radar design features that improve performance in countermeasure environments. Most military radars employ CCMs to eliminate or reduce the impact of the CMs. Network Radar Countermeasure Systems: Integrating Radar and Radar Countermeasures Jiang, Qiuxi on. Overload or confuse the radar operator or signal processor by generating large numbers of false targets, either electronically or with physical objects ĭeceive the radar operator or signal processor by using false electronic targets or physical objects, often called decoys, that resemble the targets of interest. Mask targets of interest to the radar by using, for example, electronic jamming signals or radar volume chaff A technique employed in the radar to mitigate these interfering tactics is called a counter-countermeasure (CCM), or electronic counter-countermeasure (ECCM). When it employs electromagnetic radiation such as jamming, it is called an electronic countermeasure (ECM). Such an interfering tactic is called a radar countermeasure (CM). Algorithms for optimal autonomous navigation of this nature were formulated to effectively guide the UAVs to their goal positions to meet the necessary temporal and spatial requirements.Military radar may be subjected to deliberate interference by an enemy. The will be required to arrive at these waypoints with a specific state, depending on the task at hand. The resource and data information of network radar countermeasure systems are widely shared via the network, which not only brings great convenience and flexibility of processing in target identification and target route connection, but also improves processing in terms of accuracy and real-time application. Therefore the UAV must autonomously navigate to a given goal position, subsequently perform a simple, associated task countermeasure, if required, then navigate the next goal position in the series. The goal positions may lie along a countermeasures pre-planned course or they may be established such that the UAV moves from the final waypoint of one countermeasure to the starting point of the next countermeasure. radar systems RF engineering electro-optics counter-measure development signature management signal and image processing software engineering sensor.

All tracking radars are given simplified detection properties. Network Radar Countermeasure Systems: Integrating Radar and Radar Countermeasures 303. The UAVs are assigned simplified flight dynamics and performance constraints in two-dimensions, assuming constant altitude flight over a flat-surfaced earth. This paper addresses the path planning required to meet the temporal, spatial, and UAV flight dynamics constraints associated with employing these electronic countermeasures, especially between jamming and deception activities. Previous work focused on generating a set of waypoints for the UAV to follow in order the countermeasures to be successful. Similarly, a UAV may be assigned to deceive a radar by directing a delayed signal toward the victim radar, which has the effect of producing a radar phantom perceived by the radar as an object at a false range andor bearing. A UAV may be tasked to engage a radar using noise jamming to mask its radar return or that of another vehicle. Abstract: A growing concept in the field of unmanned air vehicles UAVs is the idea of using a team of cooperating vehicles to participate in electronic countermeasures, defined here as jamming or deception techniques.
