Multistatic adaptive pulse compression

Extending the Radar Dynamic Range using Adaptive Pulse Compression

The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...

GOATS 2008 Autonomous , Adaptive Multistatic Acoustic Sensing

The MIT Laboratory for Autonomous Marine Sensing Systems (LAMSS) has continued its interdisciplinary research under the GOATS project, initiated in 1998 in collaboration between MIT and NURC, and as such a seamless continuation of the research effort under the previous grant N00014-05-1-0255. The principal opjective is to develop, implement and demonstrate real-time, onboard integrated acoustic...

Fast implementation for modified adaptive multi-pulse compression

This paper deals with the estimation of range-Doppler plane in pulse Doppler radar system, accounting both for clutter-free scenario and clutter scenario. A modified adaptive multi-pulse compression (MAMPC) algorithm including the estimation stages of range dimension and Doppler dimension is proposed for clutter-free scenario, where each stage is implemented based on the gain constraint adaptiv...

Adaptive pulse compression for transform-limited 15-fs high-energy pulse generation.

We demonstrate the use of a deformable-mirror pulse shaper, combined with an evolutionary optimization algorithm, to correct high-order residual phase aberrations in a 1-mJ, 1-kHz, 15-fs laser amplifier. Frequency-resolved optical gating measurements reveal that the output pulse duration of 15.2 fs is within our measurement error of the theoretical transform limit. This technique significantly ...
