Modern radars generally perform all of these MTI techniques as part of a wider suite of signal processing being carried out by digital signal processors. MTI may be specialized in terms of the type of clutter and environment: airborne MTI (AMTI), ground MTI (GMTI), etc., or may be combined mode: stationary and moving target indication (SMTI).
Pulse-Doppler typically uses medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. The range between transmit pulses is 5 km to 50 km. Range and velocity cannot be measured directly using medium PRF, and ambiguity resolution is required to identify true range and speed.
Knowledge is power for any pet parent, and a DNA test is the perfect place to start. Not every kit is the same, though. Along with my pup Daisy, I tested four of the most popular dog DNA kits ...
Areas outside the blue zones are blind ranges and blind velocities, which are filled in using multiple PRF and frequency agility. The unambiguous zone is in the lower left corner. All of the other blocks have ambiguous range or ambiguous radial velocity. Pulse Doppler radar relies on medium pulse repetition frequency (PRF) from about 3 kHz to ...
Adam Boyko was part of a team of scientists who in 2015 discovered that the origin of domestic dogs was near Central Asia 15,000 years ago. [19] In 2016, he was the senior author of a study by Cornell College of Veterinary Medicine researchers that was the largest genetic study of dogs to ever be completed, with a collection of samples that ...
Track while scan radars became possible with the introduction of two new technologies: phased-array radars and computer memory devices. Phased-array antennas became practical with the introduction of tunable high-power coherent radio frequency oscillators in the 1960s. By shifting the phase slightly between a series of antennas, the resulting ...
All test-drive dogs are also available for immediate adoption; you just won't receive the 50% adoption fee discount without fostering for five days first. Full-price adoptions range from about $75 ...
If the poison has only recently been ingested (within 2 to 3 hours), the dog should be given apomorphine or hydrogen peroxide to induce vomiting. Activated charcoal can be given to absorb any remaining poison in the gastrointestinal tract. Then the dog is given Vitamin K supplementation for 3 to 4 weeks, depending on the type of poison.
