In our subsequent sections, we will discuss more about these two Delay line cancellers. Single Delay Line Canceller. The combination of a delay line and a subtractor is known as Delay line canceller. It is also called single Delay line canceller. The block diagram of MTI receiver with single Delay line canceller is shown in the figure below.[PDF]

widened by passing the output of the delay-line canceller through a second delay-line canceller. The output of the two single-delay line cancellers in cascade is the square of that from a single canceller. The two-delay-line configuration has the same frequency-response characteristic as the double-delay-line canceller.

Nov 24, 2016 14 n n n n The Filtering Characteristics of a Delay Line Canceller The output of a single delay canceller is: This will be zero whenever πfdT is 0 or a multiple of π The speeds at which this occurs are called the blind speeds of the radar . where n is 0,1,2,3, 15.[PDF]
A DELAY-LINE CANCELLATION METHOD FOR CLUTTER
Using a single delay-line canceller, we subtract the echo received on DIFFERENCE beam from the echo received on SUM beam. This results in both positive and negative amplitudes at the detector output.
What is the function of the delay line canceller in MTI radar?
Apr 10, 2017Answer Wiki. It is a simple implementation of a notch filter, with nulls at 0Hz (where the clutter mostly lies) and at integer multiples of the pulse repetition frequency (prf). It thus filters out the stationary clutter leaving only the moving targets. If you cascade several delay line cancellers you can get deeper notches for better suppression.
