In this paper, we present a novel development of compact micropower ultrawideband (UWB) radar by integrating ultrashort balanced transmitter, sampling receiver, and antennas into a single package. The developed transmitter produces a pair of Gaussian pulses with 1 MHz of PRF, 400 ps of duration, and 8.3 V for peak-to-peak amplitude. The receiver down-converts microwave signals with a conversion gain of 3 dB over a 4.5-GHz bandwidth. The integrated UWB micropower radar system allows for the short-range detection with high range resolution and accuracy, thus enhance effectively the capability of target detection and classification. The high performances of such radar system for detecting objects are demonstrated through the realfield tests of various target scenes.Index Terms-Micropower impulse radar (MIR), UWB transmitter/receiver, UWB antenna, pulse generation, sample and hold circuit, nondestructive test.

“…Typically, an IR-UWB signal generator is a significant part of any modern wireless communication transceiver that uses IR-UWB signal. The literature analysis [7][8][9] of IR-UWB signal generators shows that its generalized block diagram can be presented as a serial connection between the pulse sharpener and the Gaussian monocycle forming network, as shown in Fig.5. In accordance with Fig.5, the pulse sharpener is designed to generate short-duration unipolar pulses, usually with duration of hundreds of picoseconds / units of nanoseconds, which are similar to Gaussian pulses in time domain.…”

Background. A new idea for receiving and transmitting impulse radio ultrawideband signals with Pulse Position Coding (PPC) in transmitter station and antenna decoding in receiver station is proposed. A receiving station that allows decoding the ultrawideband signal with PPC only by receiver antenna due to its construction which is spatially matched with the subscriber's PPC address sequence is described. Objective. The aim of the paper is to present the idea of ultrawideband signals transmitting and receiving based on the application of antenna decoding method of subscriber's PPC address sequence. Methods. Computer simulation of impulse radio ultrawideband signal generator by using such computer-aided design as AWR Microwave Office was used. Also mathematical tool to describe ultrawideband signal at the outputs of antenna dipoles and in the receiver was used. Results. The simulation results of the impulse radio ultrawideband signal generator with step recovery diode indicate the possibility of generating at its output a signal with a time duration less than 1 ns in 0.3-2.5 GHz frequency bandwidth and a pulse amplitude that doesn't exceed 0.3...0.45 volts. A mathematical model and graphs of ultrawideband signals for PPC depict antenna decoding method of subscriber's PPC address sequence in the receiver station. Conclusions. The proposed idea is conceptual. Its realization will give an opportunity to offer new technological solutions for the creation of next-generation radio telecommunication systems, particularly in the terahertz frequency band.

“…In this manner, a minimum of ringing around 3.6% in overshoot has been obtained. However, and unlike the generator described by Zhong and Protiva [11][12], our pulse transmitter has the advantage of producing pulses with low ringing levels and reasonably high output amplitude. These two advantages are effective in order to satisfy completely the requirement headed for getting a system having the most accurate measurement pattern.…”

Abstract.In this paper, a high power UWB monocycle generator for Non-Destructive Microwave Radar-Sensor detection is presented. The full radar system is compound with a designed UWB generator, two commercial antennas, and an oscilloscope as a receptor. The generator is composed of three essential parts-circuits, an avalanche transistor, an SRD pulse sharping and an MFN. The main idea in this work is to convert the square waveform to a driving pulse with the parameters required by the SRD pulse sharpening to obtain an output Gaussian pulse. This output pulse is converted then into a monocycle pulse. As we know, for a good range radar measurement, a high amplitude of pulse with a minimum ringing is indispensable, especially when the measurements requires many accuracies. In order to increase the pulse of the transmitter, a useful technique has been introduced; this technique consists of making the discharge path as short as possible. The applicant technique leads also to minimize the ringing in the output pulse. The measurements had been carrying out in an anechoic chamber, with the distance between 50 and 270 cm. Good Agreements between the measured and calculated results are achieved, therefore, this system can be considered very attractive in many application fields.
