Does using notch discrimination cause loss of depth?
Yes it can cause a small loss of depth, for two reasons. Firstly, the notch discriminator adds a slight amount of capacitance to the normal discriminating circuit, and this slows the detector’s response to targets. Sweep-speed then becomes more critical when seeking deep targets, but if the detector is used at the correct sweep-speed, the loss of depth will not amount to much. Secondly, Signal strength diminishes at the top and bottom edges of the notch window. As the target approaches the response cut-off of the filters used, its signal weakens. Setting the top and bottom edges of the notch window will cause some loss of depth on those targets. However, a properly adjusted notch window will not cause a great deal of depth loss.
