Low-cost position-adaptive UAV radar design with state-of-the-art cots technology
First Claim
1. An on-board based instrumentation system for position-adaptive convergence of an unmanned-air-vehicle helicopter between two structures comprising:
- an unmanned-air-vehicle helicopter;
a positional control system;
a close-range monostatic radar system for transmitting, receiving and processing in real-time a radar signal;
a system controls processor for interfacing said radar system with said positional control system and wherein said controls processor iteratively controls the location of the helicopter in real-time;
and wherein large range values from said close-range monostatic radar system correspond to leakage points and wherein said leakage points correspond to lower values of signal attenuation and higher values of medium penetration, said unmanned-air-vehicle helicopter converging and hovering at said leakage points.

Abstract
A position-adaptive radar method and device for small UAV platforms capable of detecting “leakage signals” that, for example, propagate between two buildings or “leak through” penetrable surfaces such as walls or layers of the ground. The position-adaptive radar comprises a monostatic radar receiver that measures and processes leakage signals and then “self adapts” in position to establish line-of-sight between a mini-UAV platform and an obscuration channel that propagates the leakage signal. This allows a mini-UAV platform to process signals in real-time while gathering intelligence information and locating objects-of-interest that may be embedded within an obscuration channel.
