Goldstone Radar Observations Planning: 2002 PZ39 at DSS-13


Background


163373 2002 PZ39
2002 PZ39 was discovered on 2002 Aug 10 by LINEAR.
This asteroid has an absolute magnitude of 18.9 that suggests a diameter
of roughly 0.5 km, and lightcurves obtained in early 2020 by P. Pravec suggest a very 
slow rotation period of 149 hours (6.2 days).

This asteroid will approach within 0.039 au on February 15.  Observations are scheduled at Arecibo
from Feb. 11-17 and will include reception at Green Bank, DSS-13, and elements of the VLBA. 
DSS-14 is not currently operational as a radar and will not be used for these observations.

We are expecting moderately strong SNRs for this object at DSS-13.  The SNRs at Arecibo will be strong 
enough for 7.5 m/pixel delay-Doppler imaging.  Due to the very slow rotation period, the plan at DSS-13
is to integrate for and obtain one or two imaging snapshots per track.  Integrations spanning two full
hours will smear only a few degrees in rotation.

At S-band, DSS-13 can receive only one channel: RCP.  Fortunately Arecibo transmits LCP, so this should 
work fine.

Green Bank is the primary receiver for Arecibo transmissions.  At DSS-13 we will "eavesdrop."

Pointing, Doppler, and time delay uncertainties for this object are very small. 

The Minor Planet Center has classified 2002 PZ39 as a "Potentially Hazardous Asteroid."

DSS-13 times include 60 minutes for precal and 30 minutes for postcal, except on Feb. 13, when
the start time is only 12 minutes before the asteroid rises at Arecibo due to another
project scheduled at DSS-13.

Setups


Based on monostatic results at Arecibo, we are expecting a bandwidth of less than 0.1 Hz.  


CW setup:
---------------------------------------------------------------------------
TX polarization           RCP
RCV polarization          LCP & RCP
Frequency hops:           no hopping
Bandwidth:               5000 Hz 
TXoffset                 +100 Hz
FFT                      100,000 for 0.05 Hz resolution  (one FFT every 20 seconds)
We'll probably change the FFT after we have a detection.

Imaging setups:
---------------------------------------------------------------------------
0.05 usec (20 MHz BPC)
baud              0.05 usec
code           2047 
ncoh              1
bandwidth      9770.4 Hz   
FFT         100,000 
resolution        0.1 Hz   This won't resolve the echo.  The goal here is to see an echo quickly.
TXoffset         +2 Hz
