Harmonic Radar With Adaptively Phase-Coherent Auxiliary Transmitters

Contribution of Auxiliary Coherent Radar Receiver to Target’s Velocity Estimation

Recent progress in bistatic radar techniques can be used to improve performances of classical monostatic radar. A prominent limitation of coherent radar is its inability to measure the complete velocity vector (magnitude and direction) of a detected target. A single coherent detection can provide range-rate only. At least two detections, separated in time, are needed to estimate the target’s ve...

Radar Imaging with Independently Moving Transmitters and Receivers

In this paper we present an analytic filtered-backpropagation inversion method for radar imaging when the transmitters and receivers are moving along independent flight paths. The flight paths are arbitrary, but assumed known. We assume a singlescattering model for the radar data, and we assume that the ground topography is known. We assume, in addition, that the receiver can correctly associat...

On the Coherent Phase Noise of Millimeter - Wave Doppler Radar

The phase noise is a very important index to wireless system, especially in millimeter-wave continuous wave radar systems. The phase noise of the signal, which is firstly leaked from transmitter and then mixed to intermediate frequency band by the local oscillator (Tx-IF), will worsen the sensitivity of superheterodyne radar system used for Doppler velocity detection. In this paper, the coheren...

Bistatic synthetic aperture radar using GNSS as transmitters of opportunity

Coherent Radar—Opportunities and Demands

he Applied Physics Laboratory, in its role as Technical Direction Agent for several Navy radar development programs, applies a coherent data collection and analysis methodology when evaluating system performance. Programs that have benefited from this approach include the Mark 92 Modification 6 (MK 92 MOD 6) fire control system, the Phalanx close-in weapon system, and the AN/SPS-48E surveillanc...
