Constant envelope waveform design for MIMO radar
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010 A method for generating constant envelope (CE) waveforms to realise a given covariance matrix for a closely spaced MIMO radar system is proposed. In contrast to available algorithms, the technique provides closed form solutions for finding the required waveforms and suggests that waveforms can be chosen from finite alphabets such as binary-phase shift ...

Target Recognition of Radar HRRP Using the Envelope Reconstruction
, 2017 In target recognition based on high range resolution profile (HRRP), the major challenge is to extract invariant and robust features from the measured high dimension range profile samples. Focused on the reduction of dimensionality, a novel algorithm for extracting HRRP features is proposed in this paper, and the Legendre moments with orthogonal and ...

A frequency modulated envelope delay FSCW radar for multiple-target applications
IEEE Transactions on Instrumentation and Measurement, 2000 A frequency modulated (FM) FSCW radar technique that uses the envelope delay to determine range information is described. The analysis shows that the measured delay produced by the FM FSCW system consists of a term proportional to the delay of the strongest reflection and a superimposed oscillation with a period equal to the difference in the target ...

Minimax envelope constrained filter for radar and communications applications
4th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services. TELSIKS'99 (Cat. No.99EX365), 2003 The envelope constrained filter (ECF) is a useful approach to filter design. The authors of the original concept have proposed algorithms for solving the ECF design problem as well. These algorithms use the tools of nonlinear programming. They are based on a feasible solution assumption. In other words, they perform well when the solution can be found.

Radar Pulse on Pulse Identification Parallel FFT and Power Envelope Algorithm
2020 11th IEEE Annual Ubiquitous Computing, Electronics & Mobile Communication Conference (UEMCON), 2020 Identification of pulse radar signals is a crucial component in radar receiver processing. Extracting RF radar pulse information in wideband receivers in a dense and noisy environment without prior knowledge of the signal is challenging in high-risk real-time scenarios.

Echo envelope distribution in high resolution radar imaging system
Experience of Designing and Applications of CAD Systems in Microelectronics. Proceedings of the VI-th International Conference. CADSM 2001 (IEEE Cat. No.01 EX473), 2002 An investigation of the stochastic features of radar image speckle patterns is presented in the paper. An analytical relation between the envelope distribution law of the received signal and scattering parameters of the object at radar imaging is derived.

Multicarrier radar signals with low peak-to-mean envelope power ratio [PDF]
IEE Proceedings - Radar, Sonar and Navigation, 2003 A multicarrier phase-coded (MCPC) pulse consists of N sequences of M bits each. The N sequences modulate N carriers that are transmitted simultaneously. The carriers are equally spaced. The carrier separation Df equals the inverse of the bit duration tb forming orthogonal frequency division multiplexing (OFDM).

Two‐tone continuous‐wave Doppler radar based on envelope detection method
Microwave and Optical Technology Letters, 2020 AbstractA continuous‐wave (CW) Doppler radar using two‐tone frequencies is presented for the measurement of short‐range distance. The envelope detection method is proposed to discriminate each frequency signal in the output waveform of the two‐tone CW Doppler radar sensor.

Near Range Radar Image Reconstruction Algorithm by Weighted Envelopes Transformation
IEEE Geoscience and Remote Sensing Letters, 2018 We proposed a methodology to apply inverse boundary scattering transform to process complex radar data with minimum imaging artifacts. Unlike other boundary extraction-based methods, such as shape estimation algorithm based on boundary scattering transform and extraction of directly scattered waves, the developed approach does not rely on peaks of ...
