MCS-96 pulse sequence design tracker
Density. 'Service time is a random variable,ugg stivali, similar to a negative index points (f) {e' (f0 \can be approximated as: P a (0-4 +23.4-X)% of the system,ugg boots günstig, the average service time is about 14 # s, when the signal flow for the 'million pulses / s,tory burch sale,, P25%. reduces the probability of leakage treatment methods are: (1) lower carrier frequency and pulse width from the two parameters on the optimal filter, dilute the signal flow as much as possible; (2) increase, the choice of high-speed processor. Optimization Program: (3) set to reach time FIFO buffer,true religion jeans, so that the computer processing of data is no longer a simple queuing system. The program is limited to use of the device,ugg italia, currently has 8 FIFO. I can see from the data when l <10 万 / s,. FIFO improved probability of intercept is obvious and issues of .4 application tracker of this pulse sequence has been used to test a prototype anti-radiation missile seeker up to two years, the practical application that it meets the design requirements. can track fixed PRI, but also can shake, stagger PRI tracking, wave gate width can set your own, most wavelet door widths up to ± 4 # s, with anti-frequency interference, stable and reliable performance. A applies to both the anti-radiation missile seeker, but also for wideband radar jammers. According to the characteristics of Poisson in-d, while the time interval of two or more pulses to reach the probability of a pulse than just reach the lower the probability of two or more orders of magnitude, Theory narrow band on the door can be said that there are two or more pulses are rare. However, if the pulse wave interference occurs inside the door, and before the relevant sequence of pulses, pulse tracking device to a new benchmark in this interference, resulting in forecast error, the maximum value of 2A, the next wave of door without interference, the tracking device automatically corrects the error to maintain normal track. If A is less than the difference between the two PRI sequence into the tracker, it may cause wrong with . tracker pure hardware problem also exists. Test Center Amendments Act have tried to solve this problem, but had to correct PRI value. may bring a large difference between the sequence of the PRI's wrong with. this is the current track the urgent need to control 56 * Harbin Shipbuilding Engineering Institute No. 15 to solve the problem, but with the potential of software to solve this problem is much greater than the hardware. tracker using SCM as the ability to adapt to intense signals need to be further improved , the ongoing high-speed processor with a TMS 320C25 substitute for a MCS-96 experiment. The average service time there is hope to reach 4 ~ 5s, which will greatly enhance the signal can be adapted to current density. However, I believe, in the current intensive and complex signal environment, whether it be in single chip multi-channel tracking, or a pure hardware multi-channel tracking, only the use, as sorting parameters, the signal directly to the possibility of separation is very small, in the tracker before. must have the choice of carrier frequency and pulse width filter. where possible.'s condition, plus space for filter selection and PR1.
