Abstract: A Doppler radar system includes a Doppler radar processor, a memory in communication with radar processor and a transmit/receive controller. The memory includes computer readable instructions that cause the Doppler radar processor to transmit a radar signal toward the airborne object at a frequency; receive reflected radar signals off of the airborne object, including frequencies produced as a result of Doppler effect due to relative motion between features of the airborne object and the radar system; and Fourier transform the received signals into the frequency domain. Peak frequencies and their harmonic frequency families are sorted and identified. The logarithm of the Fourier transform is calculated to generate a quefrency cepstrum. To identify features producing cyclic, periodic Doppler frequency patterns, peak quefrencies and rahmonic families associated with a quefrency peak are sorted and identified. The rotational state of the airborne object based on the identified quefrency families is determined.

Abstract: A standing clip for supporting an object in an upright position includes a flexible grip having an upper lever arm, a lower lever arm, and first and second support legs. The first support leg extends from the upper lever arm at a second end of the flexible grip, and the second support leg extends from the lower lever arm at the second end of the flexible grip.

Furthermore, each strut to node connection can be concentrated in a small area where each weld can be performed robotically from a fixed position that only requires the robotic weld head to swivel in a small operating window to reach each joint.
