Challenges To PSR
Challenges to perimeter surveillance radar include high clutter area operations. In the range of frequencies used almost all objects return some reflection from the radar. So foliage presents both a barrier to the radar energy as well as an area in which it is difficult to detect a moving target due to the high signal return from the foliage. To a degree, Doppler based radars can detect movement in such areas, as long as the component of movement velocity towards or away from the radar is significant enough to generate a signal that overcomes the foliage return signal.
Integration with other systems typically involves security control room plots of target position and control of one or more cameras. In turn, the cameras may be daylight or thermal.

Famous quotes containing the word challenges:
“The approval of the public is to be avoided like the plague. It is absolutely essential to keep the public from entering if one wishes to avoid confusion. I must add that the public must be kept panting in expectation at the gate by a system of challenges and provocations.”
—André Breton (1896–1966)
