The efficiency of Chebyshev digital nonrecursive band elimination filters in moving target indication systems
Abstract
It is noted that the devices that today serve as nonrecursive band elimination filters cannot combine a high quality of elimination with uniform transmission in the band of Doppler frequencies. This makes it necessary to find digital band elimination filters with better characteristics. Calculations are carried out showing that as an eliminator in moving target indication systems, digital band elimination filters of the third and fourth order are suitable.
