False target jamming is a type of electronic warfare technique used to deceive radar systems by generating multiple false targets on the radar screen. This method involves emitting signals that mimic the radar signatures of real targets, creating confusion and making it difficult for radar operators to distinguish between real targets and decoys.
Fake target jamming aims to overwhelm radar systems with multiple signals, forcing them to allocate resources and attention to non-existent targets, thereby reducing their effectiveness in detecting genuine threats.
Noise jamming encompasses several types of electronic warfare techniques aimed at disrupting radar, communications or navigation systems by emitting random or pseudo-random signals across a broad frequency spectrum.
Different types of noise jamming include:
- Wideband noise job: involves emitting noise signals that cover a wide range of frequencies, effectively masking genuine signals and reducing the signal-to-noise ratio in the receiver.
- Narrowband Noise Blocking: Targets specific frequencies used by radar or communications systems, emitting noise signals that interfere with reception of signals in that frequency band.
- Noise Barring: Involves continuously transmitting high-power noise signals at multiple frequencies, saturating the receiver and preventing it from effectively detecting or processing genuine signals.
The main difference between noise jamming and deception jamming is their goals and methods.
Noise jamming focuses on disrupting or masking genuine signals by emitting random or pseudo-random noise signals that interfere with radar or communications systems. It aims to degrade the performance of targeted systems by reducing their signal-to-noise ratio or saturating their receivers with unwanted signals.
Deception jamming, on the other hand, aims to deceive or confuse radar systems by transmitting signals that mimic the characteristics of genuine targets or objects.
This type of jamming involves emitting signals that simulate the radar cross section (RCS), movement patterns, or other attributes of real targets, thereby fooling radar operators or guidance systems into tracking false targets or ignoring them. genuine threats. Deception jamming may involve techniques such as generating false target yields, spoofing radar signatures, or manipulating radar tracking algorithms to create false perceptions of target location or speed.
Jamming methods can vary widely depending on the specific goals, capabilities, and technologies involved.
Some common methods of jamming include:
- Continuous wave (CW) jamming: involves the transmission of a continuous wave signal at the radar or communications frequency, causing interference and potentially saturating the receiver.
- Pulsed bundling: emits pulsed signals that coincide with the radar’s pulse repetition frequency (PRF), disrupting the timing and consistency of radar yields.
- Swept Frequency Capping: Uses signals that rapidly scan a range of frequencies, targeting multiple radar bands or communications channels.
- Point Bundling: Targets specific radar frequencies or channels with high-power signals to disrupt the detection or tracking of specific targets or systems.
- Sector Nulling: Involves steering directional antennas to null radar signals from specific directions, reducing the radar’s ability to detect targets in those sectors.
These jamming methods are used in electronic warfare scenarios to impair the operational capabilities of enemy radar, communications or navigation systems, thereby improving the survivability and effectiveness of friendly forces in combat situations
