How is the effect of sea clutter ameliorated?
The amelioration of sea clutter effects is intimately tied up with STC. For normal targets, as underlined by the radar equation, we have seen that the returned signal power varies according to 1/R4. However, the sea does not act like a normal target, as its effective RCS varies according to range.
What are the long term effects of clutter?
Which encourages us to buy more comfort items or cling tighter to the ones we currently have. So, let’s recap. 4 psychological effects of clutter, according to research are: Stress and increased cortisol levels that can become long-term. Feelings of shame or inadequacy that can lead to depression.
