Micro. Met - adc Doppler Weather Radar An Exciting Partnership for Weather Radars

Micro. Met-ADC Doppler Radars § We specialize in the designing & building of S & C-Band Doppler Weather Radars including the FULLY SOLID STATE C - Band Doppler Weather Radars. § Micro. Met-ADC radars are designed to detect precipitation, make velocity measurements, and measure the variations of the refractive index in the atmosphere that may be generated by local variations of temperature or humidity. § They have the capability of determining the phase difference between the transmitted and received pulse. The difference is a measure of the mean Doppler velocity of the particles. § They can be used for: (a) Severe weather detection, tracking and warning; (b) Surveillance of synoptic and mesoscale weather systems; (c) Estimation of precipitation amounts.

Solid State vs. Tubes ± Micro. Met-adc Radar System – – – digital, 100% solid-state clean, reliable data like a cd Micro. Met-adc § Magnetron Tube Radar – 1940’s tube technology – Intermittent data – like an old scratchy record

Maintenance Costs Solid State vs. Tubes § The Micro. Met-ADC Dop. Rad® radar system is solid state – We don’t use tubes at all. § MTBF: > 25, 000 Hrs. § The competition? 1940’s TUBE “technology” – Many others use 3 tube systems – Long term ownership costs - including repair and hardware maintenance - could exceed $500, 000 over ten years. – $18, 333 for a ‘Rebuilt’ magnetron – $30, 000 for a new Transmitter / Receiver tube – $30, 000 to have a new spare on hand Micro. Met-adc

Solid State Doppler Weather Radar WHY? § How do we do it? Larger penetrating pulse widths and incredibly sensitive receiver offsets power differences. § Better Technology: Fully coherent (transmitter and receiver) § Lower cost § More reliable § Reduced microwave dangers § Reduced interference issues § MOST OF ALL – MUCH LOWER POWER CONSUMPTION & RUNNING COST § If YOU had a tube based radar (3 different tubes), YOU would be spending $ 30 K/year (to stay in spec) for tubes alone. Not to mention the huge difference in power consumption and cost. § No Back-Up Power Generator Required. Micro. Met-adc

Beam Filling Radar Range Equation transmit power (NOTE LINEAR TERM!) for monostatic “pencil beam” single antenna = 3 d. B beam width pulse width losses (transmission, atmospheric attenuation, etc. ) Reflectivity factor MDS = -135 d. Bm @ 20 micro seconds (goes as K/ ) For false alarm rate <1 X 106 Due to integration of beam shape NOTE 1/r 2 beam filling constraint (because the target cross section had a r r term in beam filling changing the relationship to 1/r 2) (Due to integration in range and Azimuth) Micro. Met-adc

Power and Attenuation Power is only one term in the radar range equation and has no more weight than pulse width or receiver sensitivity. Therefore, a radar with 1000 times more power will produce the same range as a radar that has 100 times more sensitive receiver and 10 times bigger pulse width (all else being equal). A Micro. Met-adc radar is low power 200 W (intentionally and at great design costs), but has up to 100 times more sensitive receiver (approximately 20 d. B) and up to 10 times larger penetrating pulse width (than some magnetron based systems) - approximately 10 d. B, thus, 10 X 100=1000=30 d. B. Micro. Met-adc

Attenuation depends on temperature and wavelength, not power. It is also a function of rainfall rate and length of path. Punching power attenuation arguments for using low efficiency (microwave radiation hazard and RF interference generating) 250 KW magnetrons are very misleading. C-Band attenuation for most scenarios is being overstated. One way attenuation for 5. 5 cm (5. 4 GHz) at 0°C =(. 1349 d. B/sm)/(inch/hr)**, thus, 100 miles of 20 d. BZ rain (. 026 inches/hr) will produce a two way attenuation of just. 7 d. B and 10 miles of 40 d. BZ returns (1. 02 inches/hr) results in a two way loss of just 2. 75 d. B. (For a 10 cm NEXRAD the attenuation is (. 0376 d. B/sm)/(inch/hr) which results in. 2 d. B and. 76 d. B respectively. Therefore, the requirement for 1000 times (30 d. BZ) more punching power in terms of attenuation compensation is ludicrous. In addition, Micro. Met-ADC systems have PAC Path Attenuation Compensation that helps reduce some of the effect of attenuation through intervening rain. The higher the frequency (shorter wavelength) the more attenuation, so if other vendors operate at frequencies higher than 5440 MHz (and they do) they have greater attenuation through intervening rain than the Micro.
