“…It is very difficult to use radar pulse to measurement the far and close targets at the same time, for this reason there are long range pulsed radars cannot measure range of close target and vice versa. Also the loss decreases with increasing numbers of pulses [17,13] In figure (10) shows range or SNR versus number of coherently pulses for three choices of RCS, peak power and antenna gain. We observed that the detection range increases logarithmic with number of coherent pulses.…”

This paper deals with the minimum detection range versus maximum signal to noise ratio (SNR) for several choices parameters like (peak power percent, radar cross section (RCS), antenna gain, coherently pulses, and duty cycle) by using MATALAB simulation program, these programs have been developed to make them easy for any user of evaluating the radar range and SNR equations and make them so faster and more convenient. After enter the input these parameters, the programs will calculate the detection range and SNR of a radar system and view the result as graphically.

“…While narrow band noise radars have been proposed and refined over the past fifty years [25][26][27][28][29][30][31], the concept of UWB random noise radar has seen significant development more recently [32][33][34][35][36][37]. In contrast to conventional radar, the UWB noise radar transmits a noise or noise-like waveform having a fractional bandwidth of greater than 25%.…”

Radio frequency (RF) tags have been widely used in inventory tracking, environmental monitoring, battlefield situational awareness, and combat identification due to their low cost, small size, and wireless functionality. This paper explores the application of active RF tags in outdoor environments responding to random noise radar interrogations with predetermined messages. A conceptual system design for communication between radar and RF tags using ultrawideband (UWB) noise waveforms is proposed and analyzed theoretically and via simulations. The tag structure comprises a sensing receiver and active receiver/transmitter. The sensing receiver senses the radar header consisting of a prearranged secret realization of the noise waveform. The active receiver/transmitter modulates the RF tag's message onto the radar interrogation signal through weighted tapped delays and reradiates the tag message back to the radar. System performance is evaluated in terms of symbol error probability in an additive white Gaussian noise (AWGN) channel. A technique to combat multipath interference is presented. It is shown that this system is capable of communicating a suite of messages from the tags to the radar.
