Cohrent oscilator
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.

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.
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.
The Sea Giraffe is the navalized variant of the Ericsson(now SAAB) Giraffe Radar. It is a medium range air/surface search MTI radar.
In radar terminology, COHO stands for "COherent Heterodyne Oscillator." It refers to a type of oscillator used in coherent radar systems to mix signals and enhance the detection of targets by improving signal-to-noise ratios. This technology is crucial for applications requiring precise measurement and identification of objects.
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.
MTI Consulting was created in 1997.
The speed at which he moving target cannot be detected means uncancelled clutter interference with moving target takes place is called as blind speed. It occurs in MTI radar-----------------afsha(TE EXTC)
