BLOCK DIAGRAM OF SINGLE DELAY LINE CANCELLER

Radar Systems - Delay Line Cancellers - Tutorialspoint
Double Delay Line Canceller. We know that a single delay line canceller consists of a delay line and a subtractor. If two such delay line cancellers are cascaded together, then that combination is called Double delay line canceller. The block diagram of Double delay line canceller is shown in the following figure.

The delay line canceller is used in MTI radar system and it works as a filter. It eliminates the clutters in received signal thereby improving the resolution of target detection. The delay line canceller subtracts echoes from the successive signals.
What is the function of the delay line canceller in MTI
Older radars, before the implementation of digital memory, a single pulse of the received signal at the PRF (pulse repetition frequency), i.e., the reciprocal of the time between successive pulses was stored in the delay line . The stored signal w..

The block diagram of MTI receiver with single Delay line canceller is shown in the figure below. Radar Systems – Delay Line Cancellers One way of accomplishing this is to delay the reflected signal due to one transmitter pulse by a time interval equal to the period of the pulses and then subtract it from the reflected signal due canceler the succeeding pulse.

Delay line canceller is a filter, which eliminates the DC components of echo signals received from stationary targets. Referring to FIGURE 1, the radar system comprises generally a transmitter 10 which includes a generating means 11 for generating a series of alternating current pulse signals, and a receiver 12 which includes a delay line

Photonic-Enabled RF Canceller with Tunable Time-Delay Taps
PDF filefor single-antenna systems [4] and a single-tap canceller that can inherently only process narrowband signals [5]. This paper introduces a novel RF canceller architecture that is based on the use of photonic components to achieve both a high number of taps with tunable time-delays and a high delay spread with minimal insertion loss.Author: Kenneth E Kolodziej, Bradley T Perry, Sivasubramaniam YegnanarayananPublish Year: 2016
