For ground-based radar, cluttered returns tend to be at DC, making them easily discriminated by Moving Target Indication (MTI). [3] Thus, a notch filter at the zero-Doppler bin can be used. [2] Airborne platforms with ownship motion experience relative ground clutter motion dependent on the angle, resulting in angle-Doppler coupling at the ...
Pulse Doppler radar may have 50 or more pulses between the radar and the reflector. Pulse Doppler relies on medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. Each transmit pulse is separated by 5 km to 50 km distance. Range and speed of the target are folded by a modulo operation produced by the sampling process.
New Jersey Gov. Phil Murphy, meanwhile, said on X late Sunday that he had met with state police officials and radar technicians who are “surveying the area for unmanned aircraft systems.”
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
New Jersey’s largest utility has asked the feds to halt all air traffic over two of its nuclear power plants — after drones were spotted over the sensitive sites, The Post has learned ...
If you live in New Jersey, you can also report it to the New Jersey Office of Homeland Security and Preparedness Counter-Threat Watch Unit at 866-4-SAFE-NJ (1-866-472-3365) or tips@njohsp.gov.
Microwave Doppler frequency shift produced by reflector motion falls into the audible sound range for human beings (20–20 000 Hz), which is used for target classification in addition to the kinds of conventional radar display used for that purpose, like A-scope, B-scope, C-scope, and RHI indicator. The human ear may be able to tell the ...
MDV determines whether traffic will be detected. A GMTI radar must distinguish a moving target from ground clutter by using the target's Doppler signature to detect the radial component of the target's velocity vector (i.e., by measuring the component of the target's movement directly along the radar-target line).
