This invention is an imaging laser radar that generates a topographical image of what is in its field of view.

The design of a broadband planar magic-T using microstrip-slotline transitions is proposed. The design implements a small microstrip-slotline tee junction with minimum size slotline terminations to reduce radiation loss. The experimental results show that the magic-T provides more than 70% of operating bandwidth with the average in-band insertion loss of less than 0.6 dB. It also has phase and amplitude imbalance of less than ±1° and ±0.25 dB, respectively.

The shapes of waveforms generated by commercially available analytical separation devices, such as some types of mass spectrometers and differential mobility spectrometers are, in general, inadequate and result in resolution degradation in output spectra. A waveform generator was designed that would be able to circumvent these shortcomings.

The objective here was to prototype the next generation of end-to-end communication protocols for an Interplanetary Network using Delay Tolerant Networking (DTN) protocol suite. This includes developing both flight software for low-rate missions and an FPGA implementation of the protocol stack for the high rate missions.

The planar magic-T provides the novel realization of passive microwave/millimeter-wave signal power combining for both in-phase and out-of-phase at the H-port and at the E-port, respectively. The structure allows broadband power combining with high isolation between the in-phase and out-of-phase ports. The achieved level of isolation is high compared with any planar magic-Ts, despite its compactness.
