This paper presents a novel, cost-effective technique for estimating the Doppler effect in the time domain using a single pulse and subsequently leveraging the precise Doppler value to recover the radar waveform. The proposed system offers several ke

A visibility-modelling based method is introduced to determine the elevation and azimuth angles for a signal received at a quasi-randomly arranged (2-D) array. The method is optimal for the number of antennas when the array is configured such that no

This paper introduces a novel smeared synthesized LFM (SSLFM) time compression overlap-add (TC-OLA) radar system. The new system allows us to control the signal to noise ratio level, and, therefore, obtain a higher processing gain compared to the tra

This paper introduces a novel approach to incorporate the time compression overlap-add (TC-OLA) technique used in communication systems into linear frequency modulation pulse compression (LFM-PC) radar systems. This technique significantly boosts the

We present a UWB and spread spectrum communications method based on the idea of time compression where a sampled message signal is transmitted at a higher sampling rate. Robustness is achieved by dividing the signal into overlapping segments, transmi

A variant of time-compression overlap-add (TC-OLA) is proposed as an alternate physical layer scheme for ultrawideband communications. Although the construction of the transmitted signal is identical to other TC-OLA applications, this letter explores

A novel approach to ionospheric imaging with the purpose of weather/disaster prediction and climate study is introduced. This feasibility study combines High Frequency (HF) radio via Software Defined Radio (SDR) systems with traditional imaging techn

In this paper, a new method for detecting events in noisy hydrophone data is developed. The method takes an image processing approach to the 1D hydrophone data by first converting it into a log-frequency spectrogram image (cepstrum). This image is th

Acoustic musical instruments enable very rich and subtle control when used by experienced musicians. Musicology has traditionally focused on analysis of scores and more recently audio recordings. However, most music from around the world is not notat
