“…The above development shows that stretch processing is a special case of the proposed processing architecture. Thus, stretch processing hardware (such as that described in [19]) can easily accommodate the proposed processing architecture by simply replacing the LFM waveform with the desired NLFM waveform.…”

“…The demanding time-sampling requirements for a broadband waveform may be reduced through the use of "stretch processing" [2,4,7,9,10,14,15,18,19], if prior information is available concerning the range-window in which targets of interest may exist. Stretch processing allows a low time-sampling rate in a homodyne architecture, 1 but still achieves fine range-resolution for linear frequency modulations.…”

This paper proposes a new radar/sonar processing architecture that enables a low-rate time-sampling rate while still producing a high-resolution range profile over a narrow range-window. This new architecture generalizes the conventional "stretch processing" architecture (which employs linear frequency modulated (LFM) waveforms that suffer from high range-sidelobes), to nonlinear frequency modulated (NLFM) waveforms, which can lower the range-sidelobes without tapering. Computational results demonstrate both the estimation efficacy and the time-sampling efficiency of the proposed scheme.

“…For this reason, equipment designed for this purpose is hard to find and expensive. However, sometimes designers can use inexpensive technologies to solve the problem of measuring waveforms with very complex characteristics [15], [16]. For example, not long ago, if real-time data acquisition and signal processing was involved, it was difficult and very expensive to save a large amount of data.…”

Abstract-Alow-cost, multiple-purpose, and high-precision timing test setup for the measurements of secondary Mode S radar transmission signal was proposed. The goal was to fully guarantee compliance of the proposed transmitter under test with the really hard International Civil Aircraft Organization requirements using traditional measurement equipment, which was difficult or even impossible to ensure up to now. The low-cost structure proposed in this paper allows the user to perform measurements independently of the measurements performed by the pieces of test equipment shelled by the manufacturer of radar, which is a very important aspect since the independence of the verifications is a mandatory requirement established by the safety standards of civil aviation. The proposed setup has been used to verify several transmitters with some defects that are not detected by monopulse secondary surveillance radar specific pieces of test equipment that are focused on more high-level functionalities. It also is valid and it has been used, as a general-purpose setup, for testing other radio navigation aids. Index Terms-Commercial-off-the-shelf(COTS) equipment, differential phase shift keying, envelope and phase measurements, global positioning system disciplined oscillator (GPSDO), Mode S radar, monopulse secondary surveillance radar (MSSR), radar measurements, transmitter measurements.

“…In 2000, MIT Lincoln Laboratory funded the development of a 16-channels wideband digital array radar with two working modes, narrow band (10MHz) and broadband (>500MHz) using the stretch processing [10]. In 2013, American University of Sharjah developed a dual-channel S-band digital radar test bed using stretch processing to achieve 600MHz of instantaneous bandwidth [11]. Applied Radar, Inc. makes many development efforts aiming at increasing the bandwidth and dynamic range and enabling real-time throughput of multichannel array data.…”

This paper presents a test bed for a wideband alldigital array radar, which consists of 32 linear array apertures. The operating frequency band is 1-3GHz and the instantaneous bandwidth is 500MHz. High-speed direct RF digitization and powerful digital signal processors are utilized in the design of the system. The test bed has been implemented now with a 32elements array antenna and 8 digital receiver channels. Some experiments have been conducted and the testing results are presented in this paper. The testing results confirm the feasibility of the test bed, and guide us to carry on the remaining work of the whole system designing.
