Download or read book The Use of Frequency Agility to Achieve High Probability of Target Detection on a Single Radar Scan written by Wayne Rivers and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve high probability of detection on a single scan, noncoherent integration of video signals can be more efficient than coherent integration if frequency agility is used to decorrelate the radar return pulse-to-pulse from a slowly fluctuating target. For a required detection probability of 0.9, the potential advantage from noncoherent integration of frequency-agile returns, as compared to coherent integration of the same total pulse energy on a single frequency, is about 5 dB for Swerling Case I-II targets and 2 dB for Case III-IV targets. The potential advantage is greater when higher detection probabilities are required. A strategy usable for both Swerling Case I-II and III-IV targets and P sub D values of 0.9 to 0.99 is indicated in which the burden of coherent and noncoherent integration is partitioned during the available dwell so that the number of statistically independent samples integrated after envelope detection is between 9 and 14.

Book excerpt: Frequency Modulated Continuous Wave (FMCW) radars are a fast expanding area in radar technology due to their stealth features, extremely high resolutions, and relatively clutter free displays. This groundbreaking resource offers engineers expert guidance in designing narrowband FMCW radars for surveillance, navigation, and missile seeking. It also provides professionals with a thorough understanding of underpinnings of this burgeoning technology. Moreover, readers find detailed coverage of the RF components that form the basis of radar construction. Featuring clear examples, the book presents critical discussions on key applications. Practitioners learn how to use time-saving MATLAB® and SystemVue design software to help them with their challenging projects in the field. Additionally, this authoritative reference shows engineers how to analyze FMCW radars of various types, including missile seekers and missile altimeters. Packed with over 600 equations, the book presents discussions on key radar algorithms and their implementation, as well as designing modern radar to meet given operational requirements.
Download or read book Improvement in Target Detection with a Frequency Agile Pulsed Non coherent Radar written by Kenneth Lee Horn and published by . This book was released on 1969 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Frequency agile tracking radars have received considerable attention in the literature. Frequency agility is useful in reducing target scintillations, thereby reducing tracking errors under certain conditions. However, little attention has been devoted to the improvement that can be expected in target detection with a frequency agile radar. In the past, complete pulse-to-pulse decorrelation of the target returns has been assumed for all of the analyses concerning target detection with frequency agile radars. This assumption always implies a transmitter with a large bandwidth. This dissertation analyses a pulsed non-coherent frequency agile radar applied to Swerling's Case I target. The target model is modified by assuming time decorrelation of the returns in the latter portion of the dissertation. Partial correlation of the returns is also allowed. It is shown that random selection of the transmitted frequency from a continuous probability density function yields a significant reduction in the transmitter bandwidth requirement, when compared to previous analyses, with a negligible decrease in detection range. Two practical density functions for the transmitted frequency are studied in detail, the uniform and anti-sine distribution. However, the results are general in that the curves for detection probabilities may be applied directly to any pulsed non-coherent frequency agile radar whose transmitted frequency is obtained from a probability density function. The analysis yields a closed form solution, previously unknown, for detection probabilities in the case of Swerling's Case I target. A computer program is included which calculates detection probabilities for Swerling's Case I target modified by a time decorrelation function"--Abstract, leaves ii-iii.
