Blind speed in Moving Target Indication (MTI) radar refers to a specific velocity at which a moving target cannot be detected due to the radar's sampling rate and the Doppler frequency shift. When a target moves at this speed, its motion may produce a Doppler shift that coincides with the radar's pulse repetition frequency, causing the target to be effectively "invisible" to the radar system. This phenomenon can lead to gaps in surveillance and tracking capabilities, particularly in military and aviation applications.

What is the advantages of using a MTI with a radar?
If we use only stationery target indication radar then we can't recognize targets are whether moving or stationary. next time previous will be indicated as new object appear at another place when we don't use MTI with radar.
How can you calculate speed of radar?
Radar emissions are electromagnetic radiation that travel at the speed of light.
Is radar used for speed enforcement?
Yes, radar is commonly used for speed enforcement by law enforcement agencies. Radar devices emit radio waves that detect the speed of moving vehicles by measuring the time it takes for the waves to bounce back after hitting the vehicle. This information allows officers to identify speeders and issue citations accordingly. Radar technology is effective for monitoring traffic in various conditions and is widely utilized in speed enforcement operations.
Why coherent oscillator in MTI?
A coherent oscillator in a Moving Target Indicator (MTI) radar system is crucial because it provides a stable frequency reference that enables precise detection of moving targets against a stationary background. The oscillator maintains phase coherence, which allows the system to effectively process the Doppler shift caused by moving objects, enhancing target detection and discrimination. This stability is essential for improving signal-to-noise ratios and ensuring accurate tracking of targets in various operational environments.
What did the radar do?
radar sends electromagnetic waves and it is reflected back by the object such as a plane or a sub and based on the analysis of time and speed of wave we get the position of object. for an example of radar they used radar before pearl harbor and saw many planes, the radar operatiors thought it was a squadron of b-29's returning to base but it ended up being the empire of japan's zero's (type of lightly armored plane that sacrificed armor for speed,agility,and a better service ceiling (how high a plane can go))

What is the Radar used to eliminate clutter in navigational application?
tracking radar
What is a blind speed problem?
The blind speed is a radial speed of the airplane at which the phase shifting of the echo-signal has the value±n · 360°between two pulse periods. With blind speeds moving targets are suppressed by a MTI system like ground clutter

COHO in MTI Radar uses which freq?
The COHO (Coherent Oscillator) in an MTI (Moving Target Indicator) radar typically uses a local oscillator frequency that is twice the radar's operating frequency. This frequency is used in the radar's mixer stage to enable the detection and tracking of moving targets.
Block diagram mti radar and its working?
In an MTI (Moving Target Indication) radar system, the block diagram consists of a transmit/receive antenna, a duplexer to switch between sending and receiving modes, a radar signal processor to detect moving targets, and a display unit for visualization. The radar sends out a series of pulses and examines the return signal to detect targets with a non-zero Doppler shift, indicating movement. The radar signal processor filters out stationary clutter and focuses on moving targets, displaying their position and velocity on the radar screen.
A solution to the blind speed problem in a radar system is to?
incorporate advanced algorithms for target tracking and prediction, which can compensate for delays in data processing and provide accurate information about the target's speed. Additionally, using multiple radar sensors for redundancy can help mitigate the blind speed problem by cross-verifying speed measurements from different perspectives. Regular calibration and maintenance of radar systems are also essential to ensure accurate speed measurements.
What is a sea giraffe?
The Sea Giraffe is the navalized variant of the Ericsson(now SAAB) Giraffe Radar. It is a medium range air/surface search MTI radar.
When was MTI Consultancy created?
MTI Consulting was created in 1997.
How can you calculate speed of radar?
Radar emissions are electromagnetic radiation that travel at the speed of light.
