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...
متن کاملPulse Compression Method for Radar Signal Processing
One fundamental issue in designing a good radar system is it’s capability to resolve two small targets that are located at long range with very small separation between them. Pulse compression techniques are used in radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse. In these techniques a lo...
متن کاملX-ray pulse compression using strained crystals
The use of strained crystals to time-compress chirped x-ray FEL pulses is proposed. The chirped beam diffracts from a crystal in which the strain varies with depth. Low-Z crystals are favored to reduce absorption over the required path lengths and small Bragg angles are favored to increase the diffraction efficiency of the strained crystal. The best compression ratios found for a 230 fs, 0.5% c...
متن کاملMultiwavelength pulse generator using time-lens compression.
We demonstrate a novel method of generating a multiwavelength pulse train by use of time-lens compression. In addition to pulse compression, this time lens simultaneously displaces the pulses according to their center wavelengths, resulting in a temporally evenly spaced multiwavelength pulse train. We further demonstrate a new aberration-correction technique based on the temporal analog of a sp...
متن کاملSome Aspects of Sidelobe Reduction in Pulse Compression Radars Using NLFM Signal Processing
It is well known that in the pulse compression radar theory, the sidelobe reduction using nonlinear frequency modulation (NLFM) signal processing represents a major and present research direction. Accordingly, the main objective of this paper is to propose an interesting approach related to the design of efficient NLFM waveforms namely, a temporal predistortioning method of LFM signals by suita...
