“…The characteristics of discrete spikes are of interest, including amplitude, lifetime, spatial extent and position relative to the local clutter texture. Some of the many studies aimed at describing the properties of sea spikes include [65][66][67][68][69][70]. However, often such work primarily identifies spikes from their relative amplitudes.…”

The ability to detect small targets in sea clutter is still an ongoing challenge, even for modern radar systems. Over the past decade, the development of new radar waveforms and signal processing algorithms has been assisted by an increasingly good understanding of the characteristics of sea clutter. Nevertheless, many challenges remain in the development of robust sea clutter models that span the wide range of sea conditions and viewing geometries encountered in practice. This paper describes the current challenges with some suggestions on how they can be overcome.

“…Generally the value of Ñ 0 increases with increasing depression angle (see, for example, Grant & Yaplee, 1957;Dyer & Currie, 1974). Figure 1, illustrates this dependence for small depression angles.…”

“…The change of slope shown on this figure has been attributed to interference between direct and reflected electromagnetic waves. For extended clutter the echo signal varies with range (R) as R -3 , but if wave interference takes place the signal strength varies as R -7 (see, for example, Katzin, 1957;Dyer & Currie, 1974). The actual transition range depends upon the sea state.…”
