Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] In order to be able to detect weak moving targets such as small boats on the sea surface, the cumulative time of the adaptive detector is as long as tens of milliseconds, or even a few tenths of a second, and the corresponding cumulative pulse number is increased to tens or even hundreds (here it is assumed that the radar works at Low repetition rate mode, pulse repetition frequency within 1000Hz). Within the sub-second accumulation time, the radial velocity of the target can be considered as constant, and the target echo obeys the simple form of complex amplitude multiplied by Doppler steering vector. The contradiction between the large number of accumulated pulses and the short uniform range of the sea clutter is the main difficulty in the detection of weak moving targets in the background of sea clutter. In order to solve this problem and improve the detection ab...
